Answer 1

89.4

Explanation:

To do this, we must first understand what tangent really means. It means the opposite leg: adjacent leg. So we see that the tangent fo x degrees is 90. So we must first isolate the x. We can take the inverse tangent! So the ratio of the opposite leg to the adjacent leg is 90:1. So we take the inverse tangent of 90. This comes out to be about 89.4. So x is 89.4.
