Question

Find the value of the unknown x​

Answer 1

Given fig is a Traingle∆

We know that

Sum of Angles of a ∆ = 180°

A° + B° + C° = 180°

30°+110° + C° = 180°

140° + C° = 180°

C° = 180°-140°

Angle C = 40°

Answer 2

Answer:

• 40

Step-by-step explanation:

In triangle xyz

< zxy + < xyz + < yzx = 180 ° ( by angle property of a triangle)

=> 30 + 110 + x =180°

=> x +140° = 180° => x= 180° - 140° =40°

this is the correct answer please mark as brilliant and pleade follow me
