Problem 1:

The vertical line and the horizontal line are perpendicular to each other, so they form right angles.

x + 61 = 90

x = 90 - 61

x = 29

Problem 2:

Vertical angles are congruent. They have the same measure.

m<1 = m<2 = 93 deg

Hello there!

Question #1

(90-61)= 29

x=29

Question #2

Vertical angles are across from each other. This would show us that we would have to subtract.

360-93=(267).

(267)÷ (3)= 89.

But then, we would have t understand that these vertical angles could always be congruent which would mean that they're the same size (93)
