Question

Plz answer as soon as possible

Answer 1

hey mate!!

let angles A and B be 2x and 3x respectively as they are in ratio

so, 2x+3x=180 (linear pair)
5x=180
x=180/5
x=36


now, angle b = 2x=2*36=72

now, angle 1+ angle b = 180 (linear pair)
that is angle 1+72=180
angle 1=180-72
angle 1 =28

angle h=28 ( alternate angles)


pls refer to the diagram I have attached


hope it helps

Answer 2

$\bf{\underline{\huge{ANSWER}}}$

$\bf{\underline{GIVEN}}$

a : b

2 : 3

Let a = 2x and b = 3x

a + b = 180° { linear pair }

=> 2x + 3x = 180

=> 5x = 180

=> x = 180/5

=> x = 36°

a = 2 × 36 = 72°

a = h { corresponding angles }

ANGLE h = 72 ° $\bf{ANS}$
