The measures of the angles of a triangle are in the ratio of 2x:3x:5x as
illustrated below. What is the measure of the smallest angle in the triangle?
F. 18°
G. 20°
H. 30°
J. 36°
K. 40°
The correct answer is J.
Explanation:
2x + 3x + 5x = 180, 10x = 180, x = 18, so the smallest angle has
measure 2(18) = 36O.
