Question

Question 1: Identify m∠ABC.

A.) m∠ABC = 110°

B.) m∠ABC = 30°

C.) m∠ABC = 120°

D.) m∠ABC = 90°

Question 2: Identify the reflection of the figure with vertices P(−11,−13), Q(−17,19), and R(23,−27) across the x-axis.

A.) P (11, 13), Q (17, −19), R (−23, 27)

B.) P (11, −13), Q (17, 19), R (−23, −27)

C.) P (−13, −11), Q (19, −17), R (−27, 23)

D.) P (−11, 13), Q (−17, −19), R (23, 27)



Please give explanation and answer!

Answer 1

1. < B = 1/2 * Arc
2. Reflection across x axis. That changes the signs for y coordinates. No change for x coordinates.
