Angle 1 and angle 2 form a right angle.

The measure of angle 1 is 32°.

What is the measure of angle2?

• 58°

• 122°

• 40°

• 90°

Answer explanation

A right angle is 90°. Since angle 1 and angle 2 make up the bisected right angle they must add to 90°; therefore, 90-32=58. Angle 2 is 58°.

What is the measure of ∠Q ?

• 110°

• 150°

• 30°

• 70°

Answer explanation

∠Q is 110°. Remember the largest measurement for a protractor is 180° (a straight line). We see one ray intersects at 20° and the other ray intersects at 50°; therefore, we can calculate ∠Q by doing the following:

180° - 20° = 160°

160° - 50° = 110°
