Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees

Answer:

x = 65

Step-by-step explanation:

The sum of exterior angles of a polygon is 360°.

40 + x + 77 + 2x + 45 = 360

3x + 165 = 360 . . . . simplify

x + 55 = 120 . . . . . . divide by 3
