An acute angle of 48 ° is known in a right-angled triangle.
Since a triangle is a rectangle, the second angle is 90 °.
The sum of all the angles of a triangle is 180 °.
Find the third sharp corner.
180 ° – 90 ° – 48 ° = 90 ° – 48 ° = 90 ° – 40 ° – 8 ° = 50 ° – 8 ° = 42 °.
This means that the second acute angle is 42 °.
