Question

1. if one angle measures 65°, which of the following is its supplementary angle? a. 25° b. 95° c. 115° d. 125° 2. if one angle measures 120°, which angle is supplementary to it? a. 60° b. 30° c. 90° d. 45°

Explanation:

Question 1

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\).

Step2: Calculate supplementary angle

Let the supplementary angle be \(x\). Then \(65^\circ + x = 180^\circ\), so \(x = 180^\circ - 65^\circ = 115^\circ\).

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\).

Step2: Calculate supplementary angle

Let the supplementary angle be \(y\). Then \(120^\circ + y = 180^\circ\), so \(y = 180^\circ - 120^\circ = 60^\circ\).

Answer:

C. \(115^\circ\)
