Question

3. Find the value of x.
(7x-1)°
(6r-1) degrees

Answer 1

x = 14

Explanation:

(7x - 1)° and (6x - 1)°, lie on a straight line and are a linear pair and sum to 180°.

sum the 2 angles, equate to 180 and solve for x

7x - 1 + 6x - 1 = 180 ( simplify the left side )

13x - 2 = 180 ( add 2 to both sides )

13x = 182 ( divide both sides by 13 )

x = 14
