Question

In the figure below L || M. find X

Answer 1

x = 79

Explanation:

To find the value of x we first need to find the missing angle of the triangle in the image.

• The sum of interior angles in a triangle is equal to 180°.

101 + 29 + missing angle = 180

• Add like terms

130 + missing side = 180

• subtract 130 from both sides

missing side = 50

Now, the sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.

So the value of x:

29 + 50 = 79
