Question

In ∆ABC, ∠A = 1000 and AB = AC, then ∠B = ………. and ∠C = ………. .

​

Answer 1

Answer:

AB=AC

∠B=∠C          [Angles opposite to equal sides are equal]

In △ABC,

∠A+∠B+∠C=180o

100o+2∠B=180o

∠B=40o

Therefore,

∠B=∠C=40o

Step-by-step explanation:

Have a great day

Answer 2

$\large\bf{\underline\green{☕︎Good \: Morning☕︎}}$

Given,

AB=AC

∠B=∠C [Angles opposite to equal sides are equal] .....(1)

In △ABC,

∠A+∠B+∠C=180°

100° +2∠B=180°

∠B=40°

Therefore, ∠B=∠C=40° (From 1)
