Question

(4x – 6)°
(2x)
Equation:
X:

Answer 1

x = 31

Explanation:

2x and 4x - 6 are alternate angles and supplementary, sum to 180°, then

2x + 4x - 6 = 180

6x - 6 = 180 ( add 6 to both sides )

6x = 186 ( divide both sides by 6 )

x = 31

Answer 2

x=31

Explanation:

2x+4x-6=180

6x=180+6

6x=186

x=31
