Two Congruent angles are supplementary. The measure of each angle is?
If A+ A= 180, then...
90
To find the measure of each angle, let's first define the given information. We know that two angles are congruent, which means they have the same measure. Additionally, we are given that the two angles are supplementary, which means their measures sum up to 180 degrees.
Let's assume the measure of each angle is "x". Since the angles are congruent, we can write their measures as x and x.
To find the value of x, we can set up an equation using the given information:
x + x = 180
Simplifying the equation, we have:
2x = 180
To find x, we divide both sides of the equation by 2:
2x/2 = 180/2
x = 90
Therefore, each angle measures 90 degrees.
