Question

47. The two acute angles of a Might angled triangle are:
a) Complementary b) Supplementary

c) 90
d) a and b

Answer 1

Answer:

A.

The angles in a triangle must sum to 180 degrees. If one angle is already 90 degrees, then the other two angles must sum to 90 degrees since 180- 90 = 90. So if angle C is 90 degrees, then angle A and B must be complementary because they have to add up to 90 degrees.

Answer 2

in a right-angled triangle, the difference between the two acute angles is `(pi/15)^(c )`. In a right-angled triangle, the difference between the two acute angles is `(pi/15)^(c )`. Find the angle in degrees
