Question

Which could be the measures for the three angles of an acute triangle?

a: 40, 40, 100
b: 30, 60, 90
c: 50, 55, 75
d: 30, 30, 120

Answer 1

C, because they are all below 90, which is a right angle, and acute angle means less than 90 degree angle, and above 90 degree angle is an obtuse angle.
This is my knowledge, so I might be wrong, but, I am 90% sure I'm right.

Glad I could help, and good luck :)
