Based on the Triangle Angle Sum Theorem, the sum of the angles inside a triangle must equal 180°. Which set of angles could form a triangle?(1 point) Responses 45°, 65°, and 75° 45°, 65°, and 75° 40°, 55°, and 95° 40°, 55°, and 95° 30°, 75°, and 85° 30°, 75°, and 85° 25°, 65°, and 90°

Answer 1

30°, 75°, and 85°

Answer 2

The angles of a triangle measure 30°, 70°, and x. The Triangle Angle Sum Theorem states that the sum of the angles inside a triangle must equal 180°. Based on this theorem, what is the measure of angle x?(1 point) Responses 100° 100° 80° 80° 280° 280° 110°

Answer 3

80°

Explanation:
30° + 70° + x = 180°
100° + x = 180°
x = 80°

Answer 4

The Triangle Angle Sum Theorem states that the sum of the angles inside a triangle must equal 180°. Using this theorem, find the measure of angle B. (1 point) Responses 25° 25° 335° 335° 80°

Answer 5

We will need more information to find the measure of angle B.

Answer 6

The question is 1 point) Responses 25° 25° 335° 335° 80° 80° 45°, choose one

Answer 7

45°

Explanation: Since the sum of angles in a triangle is always 180°, if angle A is 20° and angle C is 115°, then angle B must be 45° (180° - 20° - 115° = 45°).

Answer 8

The Triangle Angle Sum Theorem states that the sum of the angles inside a triangle must equal 180°. Using this theorem, find the measure of angle C. (2 points) Responses 155° 155° 205° 205° 65° 65° 55°

Answer 9

We will need more information about the other angles in the triangle to determine the measure of angle C.
