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


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


How do you find the measure of a supplement of an angle whose measure is 64 degrees?

It is 180 -64 = 116 and 64 plus 116 = a supplementary angle of 180 degrees


M angle B equals 43 Find the measure of its complement?

180


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


In triangle ABC angle A equals 17 and angle B equals 100 what is the measure of angle C?

As we know that all angles of a triangle = 180 degrees So, Angle A + Angle B + Angle C = 180 degrees So, 100 + 17 + x = 180 Angle C = 180 - 117 Angle C=63 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.


What is the measure of an angle that is 111 degrees plus 30 degrees plus 39 degrees?

That totals 180.


What is a measure of each angle of an equilateral triangle?

all triangles equal 180 degrees so 180/3 equals 60 so, the measure of each angle of an equilateral triangle is 60 degrees.


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
