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?

Respuesta :

2x+5 = 5x - 25
subtract 2x from both sides
5= 3x - 25
add 25 to both sides
30 = 3x
divide both sides by three
10 = x
plug in 10 for one of the original equations


2(10) +5 = s
20+5 = s
25 = s

s = 25°
