<h2>Answer:</h2>
</h2>
For ∠1: Because all angles inside a triangle equal 180°, set ∠2, 68, and ∠1 equal to 180, then solve for ∠1.
∠1 = 63°
For ∠3: Subtract 93 from 180 to get ∠3
∠3 = 87°
For ∠4: Because all angles inside a triangle equal 180°, set ∠3, 49, and ∠4 equal to 180, then solve for ∠4.
<h2>∠4 = 44°
∠2 = 49°
