A = 3B + 55
A + B = 155

3B + 55 + B = 155
4B = 155 - 55
4B = 100
B = 100/4
B = 25 <===

A = 3B + 55
A = 3(25) + 55
A = 75 + 55
A = 130 <==

In RST, m R =(2x+10)°, m 5=(2x+25)°, and m T=(x-5)°.
cricket20 [7]

We know that : Sum of Angles in a Triangle is equal to : 180°

⇒ In ΔRST, The Sum of Angles ∠R , ∠S , ∠T should be equal to 180°

⇒ m∠R + m∠S + m∠T = 180°

⇒ (2x + 10)° + (2x + 25)° + (x - 5)° = 180°

⇒ (2x + 2x + x) + (10° + 25° - 5°) = 180°

⇒ 5x + 30° = 180°

⇒ 5x = 180° - 30°

⇒ 5x = 150°

⇒ x = 30°
