Question

In the given figure, AB = AC and 2B = 50°. Find ZA
В.​

Answer 1

Answer:

Angle A = 80°

Explanation:

Here is your Answer

∆ ABC is an isosceles triangle.

Hence, AB = AC.

Now, angles opposite to the equal sides are equal,

therefore Angle B = Angle C = 90° —> 1

By angle sum property of a triangle —

Angle A + Angle B + Angle C = 180°

Angle A + 50° + 50° = 180°

Angle A + 100° = 180°

Angle A = 180° - 100°

Angle A = 80°
