Answer:
Value of x = 5
Explanation:
Given:
Angle 1 = 53°
Angle 2 = 78°
Angle 3 = (10x - 1)°
Find:
Value of angle x
Computation:
Using angle sum property of triangle
⇒ Angle 1 + Angle 2 + Angle 3 = 180
⇒ 53 + 78 + (10x - 1) = 180
⇒ 131 + 10x - 1 = 180
⇒ 10x + 130 = 180
⇒ 10x = 180 - 130
⇒ 10 x = 50
⇒ x = 50 / 10
⇒ x = 5
Value of x = 5
