Question

What could the measure of the acute angles in a right triangle be?

40° and 50°
90° and 90°
25° and 65°
20° and 100°

Answer 1

50 o

Explanation:

The sum of the measure of the internal angles of any triangle is

180 o .

In a right angled triangle, one angle will be 90 o .

Since we know the measure of one of the other acute (less than 90 o ) angles, we subtract the sum of the two known angles from 180 to calculate the measure of the other acute angle.

180 − ( 90 + 40 )

180 − 130

50

Answer 2

25 and 65

Explanation:

U have established that this is a right angled triangle, so:

180- 90 = 90

an acute angle is 30 degrees or less

meaning that your answer must sum up to 90 and one of the numbers should be 30 or less
