60 degree angle is an acute angle, as angles smaller than a right angle (less than 90°) are called acute angles. In the case of a geometric angle, the arc is centered at the vertex and constrained by the sides.
Step-by-step explanation:
Let me just say this has been one of the hardest easy questions ever. First complimentary angles add up to 90°. A=60+B

Answer:
60 degree angle is an acute angle, as angles smaller than a right angle (less than 90°) are called acute angles. In the case of a geometric angle, the arc is centered at the vertex and constrained by the sides.
Step-by-step explanation:
Let me just say this has been one of the hardest easy questions ever. First complimentary angles add up to 90°. A=60+B
60+B+B=90
60–60+B+B=90–60
B+B=30
2B=30
2÷2B=30÷2
B=15
Therefore, since A=B+60 then
A=15+60
=75
