Question

Given that AB is a line segment and the angle a = 75°, work out the value of x.

The diagram is not drawn to scale.

Answer 1

Answer: x equal 21 I think

Answer 2

x = 21

Explanation:

given : angle a = 75

we need to find the value of x.

To find the value of x.

we know that it is a straight angle so the sum of angles on a line will be 180

3x + 2x + a = 180

5x + 75 = 180

5x = 180 - 75

5x = 105

x = 105/5

x = 21
