Question

Three angles have measures that add to 180°
They have the following angle measures:
m ABC = (x - 6)° m CBD = (4x — 14)*, and m DBE = 5х°.
What is the
equation to solve for x? (1 point)
A. 10х° + 20° = 180°
B. x° — 20°= 180°
C. 9x° - 20° = 180°
D. 10х° — 20° = 180°

Answer 1

The equation to solve for x can be found by adding the measures of the angles and setting them equal to 180°:

(x - 6)° + (4x - 14)° + 5x° = 180°

Simplifying this equation, we get:

10x - 20° = 180°

Therefore, the correct equation to solve for x is:

D. 10х° — 20° = 180°
