Question

4.Each of equal angles B and C of an isosceles triangle ABC is 30⁰. What is angle A?​

Answer 1

Answer:

120

Step-by-step explanation:

180 =30+30 +angle A

A=180-60

A=120

Answer 2

Answer:

A=120°

Step-by-step explanation:

The Angles B and C is equal. (Isosceles Triangle)

B=C=30°

We know the total sums of the angles of a triangle is 180°

So,

A+B+C=180°

A+30°+30°=180°. (B=C=30°)

A+60°=180°

A=120°
