Module 4A Assessment Review

Choose the correct equation for each problem.

One angle is one less than six times the measure of another. The two angles are complementary angles. Find the measure of each angle in degrees.

• x + 1 - 6x = 90

• x + 6x - 1 = 90

• x + 1 - 6x = 180

• x + 6x - 1 = 180

Choose the correct equation for each problem.

A right triangle is described as having an angle of measure six less than negative two times a number, another angle measures that is three less than negative one-fourth the number and a right angle. What are the measures of the angles in degrees?

• 90 - 6 - 2x - 3 - 1/4x = 180

• 6 - 2x + 1/4x - 3 + 90 = 180

• 90 - 6 - 2x - 3 - 1/4x = 90

• -2x - 6 + -1/4x - 3 + 90 = 180
