Question

What is the value of x? (Only type the numerical value. Do not type x= before your answer)

Answer 1

ANSWER

12

EXPLANATION

Two expressions for the angles in terms of x are given,

The first one is (10x-20)°

The second one is (6x+8)°

The two angles are angles on a straight line.

The sum of angles on a straight line is 180°.

This implies that,

$(10x - 20) \degree + (6x + 8) \degree = 180 \degree$

Group similar terms,

$10x + 6x= 180 + 20 - 8$

Combine like terms:

$16x=192$

$x = \frac{192}{16} = 12$

Therefore the value of x is 12
