Question

Given m ||n, find the value of x.
(7X+9)
(9x+5)°

Answer 1

x = 2

Explanation:

(7x + 9)° is corresponding angle to (9x + 5)° angle

Therefore:

m║n ⇒ (7x + 9)° = (9x + 5)°

(7x)° + 9° = (9x)° + 5° {subtract (7x)° from both sides}

9° = (2x)° + 5° {subtract 5° from both sides}

4° = (2x)° {divide both sides by 2°}

x = 2
