Question

Helpppppp please find the value of x

Answer 1

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign "=".

Answer 2

(90/13)°

Explanation:

Given angles are,

40° , 3x + 8° , 10x +40°

Therefore, by the problem,

=> 40° + 3x+8° + 10x+42° = 180° [ Angle sum property of triangle]

=> 3x + 10x = 180 - 40 - 42 - 8

=> 13x = 90

`= > x = (90)/(13)`

Hence, required value of x is (90/13)°
