In a triangle, the three interior angles always add to 180°
m∠R + m∠S + m∠T = 180
(2x+10) + (2x+25) + (x-5) = 180
2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30
m∠R + m∠S + m∠T = 180
(2x+10) + (2x+25) + (x-5) = 180
2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30
Since they are the angles of the triangle they should add up to 180.
angle R + angle S + angle T = 180
2x + 10 + 2x + 25 + x - 5 = 180
Combine like terms:
5x + 30 = 180
5x = 150
x = 30
SO the value of x is 30
Hope this helps :)
