Question

Pls anyone tell me
(a) part
calculate x

Answer 1

hey just follow it like this , since we know from figure that 2x+3x=180 therefore it will be 5x=180 and hence x=36 hence 2x=2×36=72

Answer 2

since it is a linear pair
2x+3x=180
5x=180

$x = {36}$
substituting valur of x,

$2x = 36 \times 2 = 72 \\ 3x = 36 \times 3 = 108$
