Answer:
24°
Explanation:
A triangle will always equal 180°. In the triangle, you can see that two angles are already measures.
Angle A = 66°
Angle B = 90° (Right angle)
Angle C = ?
You have all the info you need.
66+90 = 156
If a triangle is equal to 180°, comply subtract 156 from 180. This gives you the answer 24, and that's the measure of angle C.
Hope this helped! I just did this question on my Acellus and got it right. :)
