Question 4: x = 106

Question 5: x = 118

Step-by-step explanation:

Question 4: The exterior angles of a triangle are going to add up to 360.

128 + 126 = 254

360 - 254 = 106

x = 106

Question 5: The exterior angles of a polygon add up to 360 (a quadrilateral is a polygon).

A right-angle = 90

90 + 34 = 124

360 - 124 = 236

236 / 2 = 118

x = 118

I hope this helps! :)
