Answer:
120 degrees.
Step-by-step explanation:
The 5 exterior angles sum to 360 degrees.
So the 5th exterior angle = 360 - 4(60)
= 360 - 240
= 120 degrees.
Answer:

Answer:
x = 60°
Step-by-step explanation:
since, the triangles are complementary the sum of their measures will be 90°
now,
Answer:
(a) Because it is an exterior angle
(b) The measure of angle 2 is 72°
Step-by-step explanation:
Angle 2 is an exterior angle because it is adjacent to the interior angle 1, and an exterior angle is equal to the sum of the measures of the two nonadjacent interior angles:
<2=30°+42°
<2=72°
