Find the value of x. given: rs=st, m∠rst=7x-54, m∠stu=8x  s  δ_urta.14 b.152 c.16 d.19

Given:

∠STU = 8x 
∠RST = (7x – 54) 

Solution:
∠SRT + ∠RST = 8x (exterior angle is sum of interior angles) 
∠SRT + (7x – 54) = 8x 
∠SRT = 8x – (7x – 54) 
= x + 54 

∠STR + ∠STU = 180 is the linear pair 

x + 54 + 8x = 180 

9x = 126 

x = 14
