X=?

m-A=?

m-B=?

m-C=?

Answer 1

m-A=25

m-b=65

m-c=50

Explanation:

Find the value of x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle ABC

substitute the given values

Solve for x

step 2

Find the measure of angle B

we know that

substitute the value of x

step 3

Find the measure of angle C

we know that

substitute the value of x
