If angle A plus angle B equals 90 degrees then A and B are what kind of angles?
Complementary.
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
Given a paralleogram ABCD angle A equals 30 plus 5x and angle D equals 15 plus 10x What is x?
9 degrees
If m angle Abe equals 6x plus 2 and m angle dbe equals 8x - 14 find m angle Abe?
50 Degrees
What is the supplement pf a 45 degree angle?
plus the angle degrees with the angle complement so equals into 135 degrees
If angle A plus angle B equals 90 degrees then A and B are what kind of angles?
Complementary.
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.
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
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
Two angles are supplementary the first angle measure 60 degrees what is the measurement of the second angle?
120 Since the measures of the angles of supplementary angles add up to 180, 60 plus something else equals 180. 180-60=120
If angle A plus angle D equal 90 then A and D are what type of angles?
Acute
Given a paralleogram ABCD angle A equals 30 plus 5x and angle D equals 15 plus 10x What is x?
9 degrees
Angles X and Y are supplementary If the measure of angle X equals 2x plus 4 and the measure of angle Y equals 4x plus 20 then what is the measure of each angle and why?
X = 180 - Y so 180 - Y = 2x + 4 and Y = 4x + 20 so 180 - 4x - 20 = 2x + 4 therefore 6x = 156 so x = 26 making Angle X = 56o and Angle Y = 124o
What quadrilateral has two right angles only one set of parallel sides and no lines of symmetry?
It is a trapezoid that can have two right angles plus one obtuse angle plus one acute angle and the four angles add up to 360 degrees.
What is the angle between a equals 2i plus 2j-k and b equals 6i-3j plus 2k?
36.64
If m angle Abe equals 6x plus 2 and m angle dbe equals 8x - 14 find m angle Abe?
50 Degrees
In parallelogram ABCD if angle A equals 5x plus 30 and angle D equals x find angle c?
In parallelogram ABCD, angle A and angle D are adjacent or consecutive angles and are supplementary, meaning the sum of their measures is equal to 180 degrees. Angles A and C are opposite angles and have the same measure. These are some important properties of parallelograms. So to find the measure of angle C, you first have to find the measure of angle A. You can do that with a little algebra. First, set the expressions for the measures of angles A and D equal to 180 and solve for x. Then plug that value for x into the expression for the measure of angle A, which is the same as the measure for angle C. 5x + 30 + x = 180 6x + 30 = 180 6x = 150 x = 25 Therefore, 5x + 30 = 5(25) + 30 = 125 + 30 = 155 The measure of angle C is 155.
