Question

Find the value of x in the figure
(X+5)* 90*

Answer 1

x = 85 deg

Explanation:

We can see that there are two straight lines that intersect and that the two angles given are opposite angles.

Because they are opposite angles, the two angles have the same value, i.e

(x + 5) = 90 (subtract 5 from each side)

x = 90 - 5

x = 85 deg
