Answer:
D
Step-by-step explanation:
Let
If angle A of the triangle is 1/3 as big as angle B, then
. If angle C was bigger than angle B, then
Consider all options:
A. 30°, 60°, 90°. Angles 30° and 90° can be anglea A and B, But 60°<90°. False.
B. 25°, 55°, 100°. Here are no angles such that one of them is three times greater. False
C. 20°, 60°, 110°. Since 20°+60°+110°>180°, these angles cannot be triangle's angles. False
D. 15°, 45°, 120°. If
then
and
True
Answer: 23.6
Step-by-step explanation:
