Question

2. If the angles (4x+4)' and (6x-4) are the supplementary angles, find the value of 'x'.​

Answer 1

Answer:

4x+4+6x-4=180

10x=180

x=18

Answer 2

$\huge\underbrace\mathrm\blue{∆nswer}$

Solution:

(4x + 4)° + (6x – 4)° = 180° (∵ Sum of the supplementary angle is 180°)

⇒ 4x + 4 + 6x – 4 = 180°

⇒ 10x = 180°

⇒ x = 18°

Thus, x = 18°
