The angles of a triangle are (x-35), (x-25) and (1/2x-10). Find x.

by

(A) 70
(B) 80
(C) 100 
(D) 90

🧠 Explanation (Math):

Given: Angles (x − 35), (x − 25), (x/2 − 10); find x
Step 1: Sum = 180 ⇒ (x − 35) + (x − 25) + (x/2 − 10) = 180
Step 2: 2.5x − 70 = 180 ⇒ 2.5x = 250 ⇒ x = 100
Final Answer: 100
