An interior angle and an adjacent exterior angle of a polygon form a linear pair.

How can you use this fact as another method to find the measure of each exterior

angle in Example 6?

30°

Step-by-step explanation:

Interior angle + exterior angle = 180

Because they form a linear pair.

Exterior angle = 180 - interior angle

= 180 - 150

= 30°

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
