Question

If there is one obtuse angle, how many angles are

acute?
a 2
b 3
C 1
d 6

Answer 1

Answer: a .2

Step-by-step explanation: A triangle is 180 degrees. If one angle is obtuse, it is more than 90 degrees. That leaves the two remaining angles having to add up to less than 90 degrees combined. So both have to be acute.
