Chapter 1 - Section 1.1 - Angles, Degrees, and Special Triangles - 1.1 Problem Set: 9

Answer

$ 10^{\circ}$ is an acute angle. Complement of $ 10^{\circ}$ = $ 80^{\circ}$ Supplement of $ 10^{\circ}$ = $170^{\circ}$

Work Step by Step

Angles that measure between $0° $and $90° $ are called acute angles. Complement of $ 10^{\circ}$ = $ 90^{\circ} - 10^{\circ}$ = $ 80^{\circ}$ (Because sum of the measures of complementary angles is 90 degrees) Supplement of $ 10^{\circ}$ = $ 180^{\circ} - 10^{\circ}$ = $ 170^{\circ}$ (Because sum of the measures of supplementary angles is 180 degrees)
