Acute angles can be formed when two rays extend from a common point. It is less than 90 degrees.for more information head to our twinkl teaching wiki. ∠bac = ∠a = 40°. As we know, the sum of the interior angles in a triangle is 180°, thus, in abc, ∠abc + ∠bca + ∠cab = 180°, here ∠abc = 60°, ∠cab = 60°. 263k views 8 years ago geometry | 4th grade | khan academy.
