Question

The base BC of isosceles triangle ABC is extended

through C to D. If mLACD = 108, what is
the number of degrees in the measure of vertex
angle A ?

Answer 1

Answer:29

Explanation:

Answer 2

angle of A is 36°

Explanation:

ACB = 180° - ACD ( angle in a straight line is 180°)

= 180° - 108°

= 72°

ACB = ABC (isoceles triangle)

BAC = 180° - ACB - ABC (angle in a triangle is 180°)

= 180° - 72° - 72°

= 36°
