Question

Calculate the missing angles and give a reason for your answer

Answer 1

Answer:

72°

Step-by-step explanation:

the top angle in the triangle=36° because alternate angles are equal

the triangle is an isosceles triangle hence the base angles are equal

the sum of angles in a triangle is 180°

180°=(36+i°+i°)

180=36+2i°

2i°=180-36

2i°=144

i°=144/2

i°=72°
