Question

if m‖n angle 9；angle B=2：3 the measure of h is .72° 108° 120° 150°​ plz answer quick its urgent

Answer 1

Answer:

108°

Step-by-step explanation:

let angle a be 2x

angle b be 3x

angle a + angle b = 180° (adjacent angles are supplementary on a straight line)

2x + 3x = 180°

5x = 180°

x = 180°/5 = 36°

Therefore angle b = 3 × 36° = 108°

angle c = angle b (vertically opposite angles)

which implies angle c = 108°

m||n and l is transversal

Therefore angle h = angle c

So angle h = 108°
