What is the measure of

C. 32°

Step-by-step explanation:

As the measure of sides A and C are both 10, this triangle is an isosceles triangle.

This means that the measure of ∠A and ∠C will also be equal.

As ∠A = 74, ∠C = 74

Now that we have two of the angles, we can solve for the third angle.

Recall that there are 180° in a triangle, so we can create the following equation

Now, we just need to solve for B

it has the same slope and a different y-intercept

hope this : )
