Question

circle the groups of angle measures that represent a right triangle. 25°,90°,75 40°,90°,50° 60°,60°,90° 90°,35°,55°

Explanation:

Step1: Recall triangle - angle sum property

The sum of the interior angles of a triangle is 180°. A right - triangle has one angle equal to 90°.

Step2: Check the first set

For the angles 25°, 90°, 75°, $25 + 90+75=190
eq180$.

Step3: Check the second set

For the angles 40°, 90°, 50°, $40 + 90+50 = 180$.

Step4: Check the third set

For the angles 60°, 60°, 90°, $60 + 60+90=210
eq180$.

Step5: Check the fourth set

For the angles 90°, 35°, 55°, $90 + 35+55 = 180$.

Answer:

40°, 90°, 50°; 90°, 35°, 55°
