In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°, what is the measure of ∠Y?

142°
To find the measure of ∠Y, you can use the fact that m∠E ≅ m∠Y.
Since m∠E = 62°, and m∠X = 80°, you can use the fact that m∠F ≅ m∠X to find the measure of ∠F.
So, ∠F = 80°.
Now, since ∠F and ∠Y are corresponding angles in similar triangles EFG and YXZ, the measure of ∠Y is the same as the measure of ∠F.
Therefore, the measure of ∠Y is 80°.
