supplementary angles
The angles are supplementary if they have a sum of 180 degrees.
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
A+b=180 x+2x=180 3x=180 x=60
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°
It can have any value in the range (0, 180) so it can be acute, right or obtuse.
The angles are supplementary if they have a sum of 180 degrees.
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
I am pretty sure they would be considered supplimentry angles. m<1+m<2=180 : definition of supplimentry
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
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.
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.
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°.
Angle a plus angle b subtract from 180 equals angle c
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
angle+angle+angle=180 degree then'a+b+c=180 degree example: Q what is the angle of a triangle,if a=50,b=60? answer:a+b+c=180 degree a+50+60=180 degree a+110=180 degreea=180-110 a=70 degree please answar my question
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.
The measure of the third angle in a right triangle with one interior angle measuring 51.1° is 34.9°. By definition, all triangles have interior angles that add to 180°. Thusly: Angle A + Angle B + Angle C = 180° Also by definition, a right triangle has one angle that measures 90°. Therefore 90° + Angle B + Angle C = 180° We know the measure of one of our angles, so... 90° + 55.1° + C = 180° Combine the two known angles... 145.1° + C = 180° Subtract 145.1° from both sides to solve for C 145.1° - 145.1° + C = 180° - 145.1° C = 34.9°
