Question

Given m||n, find the value of x.
1
(7x+3)
(8x+1)°

Answer 1

x = 2

Explanation:

Angles (7x + 3)° and (8x + 1)° are corresponding angles

Therefore:

m║n ⇒ (7x + 3)° = (8x + 1)°

(7x)° + 3° = (8x)° + 1° {subtract (7x)° from both sides}

3° = x° + 1° {subtract 1° from both sides}

2° = x°

x = 2
