Question

The measures of the angles of a triangle are shown in the figure below. Solve for x.

(3x+13)
(8x+14)
109°

Answer 1

The vale of x=4

Explanation:

We know that the sum of angles of a triangle = 180°

Given

• (3x+13)

• (8x+14)

• 109°

Thus, the equation becomes

(3x+13) + (8x+14) + 109° = 180°

11x + 27 + 109° = 180°

11x = 180°- 109° - 27

11x = 44

x = 4

Thus, the vale of x=4
