△ABC has a&gt;b&gt;c. If one of the angles in the triangle is 60°, name the angle that can be equal to 90°.
Aleksandr-060686 [28]

Answer:

Angle A

Step-by-step explanation:

a is greater than b, which is greater than c

a triangle has 180 degrees

so 180-90 is 90

90-60 is 30

a>b>c

90>60>30

this would be a right triangle since one of the angles is 90 degrees
