Which best explains whether a triangle with side lengths 2 in., 5 in., and 4 in. is an acute triangle? The triangle is acute because 22 + 52 > 4^2. The triangle is acute because 2 + 4 > 5. The triangle is not acute because 22 + 42 < 5^2. The triangle is not acute because 22 < 42 + 5^2.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

choice b is correct

step-by-step explanation:
