Question

Angle S and angle T are congruent. Angle S measures 2x + 5 and angle T measures 5x – 25. What is the measure of angle S?

Answer 1

Set them equal to each other.
2x + 5 = 5x - 25
Can you solve it now?

Answer 2

congruent means that the measure of an angle is equal to the other. angle S is congruent to angle T so angle S = angle T.
2x + 5 = 5x - 25
solve for x

Answer 3

thank you once again XD

Answer 4

No Problem :)

Answer 5

although remember that you're looking for angle S and not just x. So after you find x substitute it into the equation of angle S
