Lesson 2: Practice Problems

Problem 1

Angles $A$ and $C$ are supplementary. Find the measure of angle $C$ .

Two separate angels - one is 74 and the other is an obtuse angle.

Problem 2

A rectangle CDFG and a center point of DF, M. Two lines extend from M to C and G. Angle MCD is 27 deg. Angle MGF is 26 deg. Angle DMC is 63 deg. Angle GMF is 64 deg

List two pairs of angles in square $C D F G$ that are complementary.
Name three angles that sum to $180^{\circ}$ .

Problem 3 From Unit 6 Lesson 22

Complete the equation with a number that makes the expression on the right side of the equal sign equivalent to the expression on the left side.

$5 x - 2.5 + 6 x - 3 =$ $(2 x - 1)$
