A right triangle has one angle that measures 80°. What is the measure of the other acute angle? _____°

Triangle Sum Property: We know that the sum of angles in a triangle is 180°. Since it's a right triangle, one angle is 90°. The other two angles are acute and must add up to 90° because 180° - 90° = 90°. Finding Second Acute Angle: Given one acute angle is 80°, let's find the other. Subtract the known acute angle from 90°: 90° - 80°. Calculating Second Acute Angle: Doing the subtraction, 90° - 80° = 10°. So, the measure of the other acute angle is 10°.

Q. A right triangle has one angle that measures

80^\circ

. What is the measure of the other acute angle?

\newline

_____

^\circ

Triangle Sum Property: We know that the sum of angles in a triangle is $180^\circ$ . Since it's a right triangle, one angle is $90^\circ$ . The other two angles are acute and must add up to $90^\circ$ because $180^\circ - 90^\circ = 90^\circ$ .
Finding Second Acute Angle: Given one acute angle is $80°$ , let's find the other. Subtract the known acute angle from $90°$ : $90° - 80°$ .
Calculating Second Acute Angle: Doing the subtraction, $90° - 80° = 10°$ . So, the measure of the other acute angle is $10°$ .
