You know that ∠1 + ∠2 = 90° because they are crossing the vertex of a square.
Find m∠2.

90 - 72 = 18
m∠2 = 18°

Now ∠2 + ∠3 must equal 180° because they are on a straight line.
Subtract 18 from 180.
180 - 18 = 162

m∠3 = 162°

Answer:


Step-by-step explanation:

To find angle 3, we need to first find angle 2.

-It is given that it's a square. The full angle is 90°. Angle 2 would be 90-72, which is 18°.

Now that we have angle 2, we can find angle 3 because angle 2 and 3 are linear pairs.

180°-18°

162°

m<3=162°
