Question

In the following diagram, find the measures of both x and y. Line I is perpendicular to line m

Answer 1

x = 22.5 and y = 9

Explanation:

Since the lines are perpendicular then the angles formed are right, hence

4x = 90 ( divide both sides by 4 )

x = 22.5

and 10y = 90 ( divide both sides by 10 )

y = 9
