Question

Given that AB is a line segment and the angle

y
= 67°, work out the value of the angle marked
x

Answer 1

x = 113°

Explanation:

AB is a line segment and hence it is a straight line which means it is a straight angle, so it is 180° .

y = 67°

x = ?

So, x + y = AB

=> x + 67° = 180°

=> x = 180° - 67°

=> x = 113°

Therefore, x = 113°
