Question

if one of the CO interior angle is 4 times of the other then find both angles​

Answer 1

Step-by-step explanation:

4x+x=180(sum of the int.angles are 180 degree)

0r, 5x=180

or, x=36

angles are 144, 36

Answer 2

Answer:

$let \: the \: one \: co - interior \: angle \: be \: x \\ the \: second \: co - interior = 4x \\ \\ then..... \\ = > x + 4x = 180 ^{0} \\ = > 5x = 180 ^{0} \\ = > x = \frac{180}{5} \\ \\ = > x = 36^{0}$

Therefore....

First angle=36°

Second angle=144°
