Question

define the following..............​

Answer 1

Answer:

As BC and AC are equal, then angle A will also be equal to angle B .hence angle B = 40°

(- property of isosceles triangle)

Explanation:

As the sum of all interior angles of a triangle is 180° hence angle BCA = 180° - (40 + 40)°

= 180° - 80°

= 100°

Angle DCE will be equal to angle BCA and therefore, measure of angle DCE is 100°

Hope this helps.

have a great day.
