Question

The side BC of triangle is produced toD.if angle ACD =108,angle B=1/2 angle a than angle a is

Answer 1

Answer:

angle a will be 72

Step-by-step explanation:

by exterior angle property

angle a + angle b = angle acd

therefore,  a+1/2*a = 108

2a+a/2 = 108

3a = 108*2

a = 216/3

a = 72
