Question

Error Analysis On a math test the students are given a right triangle, One of the acute angles has a measure of 58°. One student says that the measure of the

other acute angle is 122°. What is the measure of the other acute angle? What error might the student have made?
The measure of the other acute angle is

Answer 1

32°

Explanation:

The error the student made is that one of the angles must be a right angle(its a right triangle) and there are 3 angles in a triangle the student though there were only 2 angles. the student took 180-58 and got 122 which is incorrect because there are 3 angles not 2.

To find the other angle you take 180 and subtract 90 and 58 from it.

180-90-58=32

the other acute angle is 32°
