Question

Draw △ABC in which ∠A = 120 degre, AB = AC = 3 cm. Measure ∠B and ∠C.
step by step explanation ​

Answer 1

Answer:

Given:A=120

AB=AC=3cm

In ABC ,

AB=AC=3(given)

B=C(opposite angles of equal sides are equal)---(1)

Sum of all the sides in a triangle is 180(angle sum property)

angle A + angle B+ angle C=180°

120+ angle B+ angle C=180°

120+angle B+angle B=180{from (1)}

2angleB=60°

angleB=30°

angleB=angle C=30°
