Question

Find the value of x in the figure below.
(8x + 5)°
(13x – 14)°

Answer 1

x = 9

Explanation:

The question is shown in the attached figure.

We can see that, (8x + 5)° and (13x – 14)° forms a linear pair. It would mean that,

(8x + 5)° + (13x – 14)° = 180°

21x-9 = 180°

21x = 180° + 9

21x = 189

x = 9

Hence, the value of x is 9.
