Question

Angle of a linear pair are in the ratio 4:5.what is the measure of each angles?

Answer 1

hi

let angles be 4x and 5x

$4x + 5x = 180 \: (linear \: pair)$

$9x = 180°$

$x = \frac{180°}{9}$

$x = 20$

$\bold{so \: angles \: are \: 4 \times 20 = 80° \: and \: 5 \times 20 = 100°}$

$\huge{hope \: it \: helps}$

Answer 2

let the angles be 4x and 5x.

4x+5x=180°.

9x=180°.

x=180/9.

x=20.

1st angle =4x=4×20=80°.

2nd angle=5x=5×20=100°

hope it helps you
