That would be 106.5 degrees
1 . 48 is the answer as the two bottom ones are equal 180-66-66=48
2. 117 degrees as the angle is the same as the other congruent angle shown in the diagram
20 x 1.151 would be 23.02 but rounded it would be 23 I think
D. y + 8 = 3(x + 1)....it has a slope of 3, and when u sub in (-1,-8), both sides come out equal. So D is ur answer.
The lines that cross or intersect at 90 degrees are called perpendicular lines. These lines form a right angle
