Question

In the isosceles triangle ABC, angle A=110° What are
the measures of angle B and angle C?​

Answer 1

In an isosceles triangle, angles B and C have the same measure, which can be found by subtracting angle A from 180° and dividing the result by 2. In this case, angle B = angle C = 70°.

Step-by-step explanation:

In an isosceles triangle, the two base angles are congruent. Since angle A is 110°, and the triangle is isosceles, angles B and C must have the same measure.

To find the measures of angles B and C, we subtract angle A from 180° (since the sum of the angles in a triangle is 180°) and then divide the result by 2.

So, angle B = angle C = (180° - 110°) / 2 = 70°.
