• 43
• 37
• 143
• 7.6666...

Find the measure of angle 1.

• 28^o
• 136^o
• 44^o
• 6^o

What is the value of y?

• 29
• 119
• 58

What is the measure of ∠8?

• 55
• 155
• 135
• 45

Find x, then find the measurement of both angles.

• x = 30; both angles measure 118 degrees

• x = 30; both angles measure 114 degrees

• x = 20; both angles measure 112 degrees

• x = 20; both angles measure 110 degrees

Solve for x.

• 4
• 9
• 10
• -7
