​

Answer 1

Hey Mate,♥️

Here Is Ur Answer......✌

One of Euclid's theorems is that the base angles of an isosceles triangle are congruent (equal). An isosceles triangle is a triangle in which two of the sides are conguent (equal). The base angles are the angles opposite the two congruent sides.

in triangle ABC if angle B and Angle C are base angles and Angle A is the vertex angle

so here angle B= ANgle C = 55degress

we know sum of angles in triangle are 180 degreess

therfore Angle A + Angle B +Angle C = 180 degrees

Angle A +55+55 = 180

Angle A = 180 - 110

Angle A = 70 degrees..
