Classify the angle as acute, right, obtuse, or straight.

That angle is acute.

Step-by-step explanation:

Our eyes tell us that the angle is less than 90 degrees. That's the definition of Acute.

A right angle = 90 degrees.

An obtuse angle is larger than 90 degrees.

A straight angle is a line which = 180 degrees.

∠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°
