Question

m∠1= 3m∠2
m∠3=100
Find∠2

Answer 1

$\blue{\bold{\underline{\underline{Answer:-}}}}$

m∠2= 20°

$\pink{\bold{\underline{\underline{<strong><u>Giv</u></strong><strong><u>e</u></strong><strong><u>n</u></strong>:-}}}}$

m∠1= 3m∠2

m∠3=100°

$\green{\bold{\underline{\underline{To<u><strong> </strong><strong>Find</strong></u><strong>:</strong>}}}}$

m∠2

$\purple{\bold{\underline{\underline{Solution:-}}}}$

∠1+∠2+∠3= 180° (We know that in a traingle)

so, ∠1+∠2+100°= 180°

or, 3∠2+ ∠2 = 180°- 100° = 80°

or, 4∠2 = 80°

or, ∠2 = 80÷4

so, ∠2 = 20°

Hence, measure of ∠2 is 20°.
