If in angle A plus measure angle B equals 180 then angle A and angle B are?
The angles are supplementary if they have a sum of 180 degrees.
Can two obtuse angle be supplementary angle?
It is not possable for two obtuse angles to be supplementary. This is because an obtuse angle is an angle greater than 90 degrees but less than 180 degrees while a supplementary angle is an angle which, when added to an existing angle will sum to 180 degrees. This can be explained mathematically, If A + B ≠ 180 where A and B are both obtuse. In this equation, there are constraints on both variables in this equation. These are, a). A + B ≠ 180 b). 180 > A > 90 c). 180 > B > 90 If we look at (90 + ∞-1) + (90 + ∞-1) you do not get 180, which would mean that two obtuse numbers could be supplementary, but you get 180 + 2∞-1 which by definition is An angle larger than two right angles but less than a full circle (between 180° and 360°" - see http://en.wikipedia.org/wiki/Reflex_angle#Types_of_angles
If two angles are supplementary and one angle is twice as large and the other find the number of degrees in the measure of the smaller angle?
A+b=180 x+2x=180 3x=180 x=60
In triangle ABC angle B is three times angle A and angle angle C is three degree less than six times angle A find the angles?
You can work this out with the knowledge that the sum of the angles in a triangle will always be 180°. We know then that A + B + C = 180°. We are also told that: "angle B is three times angle A", which means: B = 3A "angle C is three degrees less than six times angle A", which means: C = 6A - 3° We can then work out the value of A by plugging those two equations in to the first one. Once we have that, then the values of the other two angles can be worked out as well: A + B + C = 180° ∴ A + 3A + 6A - 3° = 180° ∴ 10A = 183° ∴ A = 18.3° B = 3A ∴ B = 3(18.3°) ∴ B = 54.9° C = 6A - 3° ∴ C = 6(18.3°) - 3° ∴ C = 109.8° - 3° ∴ C = 106.8°
What is the sum of the measures of the angle in any triangle is 180 degrees - in triangle ABC angles A and B have the same measure while angle C is 42 degrees larger than each other two angles?

If in angle A plus measure angle B equals 180 then angle A and angle B are?
The angles are supplementary if they have a sum of 180 degrees.
How do you determine the third angle of a triangle if 2 angles are known?
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
If in angle A plus the measure of angle B equals 180 then angle A and angle B are what angles?
I am pretty sure they would be considered supplimentry angles. m<1+m<2=180 : definition of supplimentry
What is the measure of C if A is 40 and B is 70 in a triangle?
In a triangle, the sum of the interior angles is always 180 degrees. If angle A is 40 degrees and angle B is 70 degrees, you can find angle C by subtracting the sum of angles A and B from 180 degrees: C = 180 - (A + B) = 180 - (40 + 70) = 180 - 110 = 70 degrees. Thus, the measure of angle C is 70 degrees.
What is the third interior angle of triangle?
Let the angles be a, b and c There are 180 degrees in a triangle: 180-(a+b) = c 180-(a+c) = b 180-(b+c) = a
The measure of one angle is seven more than three times he measure of another angle if the two angles are supplementary find the positive difference of the measures of the two angles?
Angle 'A' is 7 more than 3 times angle 'B': A = 3B + 7 The angles are supplementary: A + B = 180 or A = (180 - B) (180 - B) = 3B + 7 180 = 4B + 7 173 = 4B B = 43.25 degrees A = 136.75 degrees Their difference is 93 degrees.
In this parallelogram the measure of angle b is twice the measure of angle a What is the measure of angle a?
The adjacent angles of a parallelogram are supplementary. This means that angle A + angle B = 180 deg.Since angle B = 2*angle A, then angle A + 2*angle A = 180 deg ie 3*angle A = 180 deg so that angle A = 60 deg.
Identify the pair of angles show in the figure?
Two angles are said to be complementary angles if their sum is 90 degrees. The angles A and B shown in the figure are complementary since their angle sum is 90°. + B = 90° B Two angles are said to be supplementary angles if their sum is 180 degrees. The angles A and B shown in the figure are complementary since their angle sum is 180°.
If angle a and B are supplementary angles and angle a is two times as large as angle B find the measures of angle and angle B?
If angles A and B are supplementary, their measures add up to 180 degrees. Let angle B be ( x ). Then angle A, being twice as large, is ( 2x ). Setting up the equation, we have ( x + 2x = 180 ), which simplifies to ( 3x = 180 ). Solving for ( x ), we find ( x = 60 ) degrees for angle B, and angle A measures ( 120 ) degrees. Thus, angle A is 120 degrees and angle B is 60 degrees.
Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
What are measures of two supplementary angles if angle A is 5 less than 4 times the measure of angle B?
from the given information,we get, angle b = x angle a = 4x - 5 we know that supplementary angles have 180 degree as their sum , so, 4x - 5 + x = 180 5x - 5 = 180 5x = 185 x = 37 so,angle a = 4x - 5 = 4 *37 -5 = 143 angle b = 37 also angle a + angle b = 143 + 37 = 180
How do you find the unknown angle when one angle is given and the other angles are known in the form of ratios are given?
Suppose you are given one angle A and the ratio is R so that the other two angles are B and BxR.Then: A + B + BxR = 180.B (1 + R) = 180 - Aso the answer is B = (180 - A) / (1 + R)e.g. you are given A=60 and R=2so B = (180 - 60) / (1 + 2) = 40 and the last angle is 80.
