Question

If m 1 = 72°, then find the value of m 3 a) 72°b) 108°c) 144°d) 18°

Answer 1

Step 1

Given;

`m\angle1=72^o`

Required;

`To\text{ find m}\angle3`

Step 2

Find the required angle.

`^{}m\angle3=72^o(vertically\text{ opposite angles are equal)}`

Hence, the measure of angle 3 = 72 degrees
