Find the value of X in the triangle.
-40x + 18
- 20x + 3
15x + 92

Explanation:

If -40x + 18, -20x + 3 and 15x + 92 angles of a triangle.

Then -40x + 18 + -20x + 3 + 15x + 92 = 180°, by angle sum property of a triangle

-40x + 18° + -20x + 3° + 15x + 92° = 180°

(-40x -20x + 15x) + (18° + 3° + 92°) = 180°

(-60x + 15x) + 113° = 180°

45x = 180° - 113°

45x = 67°

x = 67°/45

x = 1.48

x = 1.5(rounding off)
