Assume ABC DEF. If mA = 70, mB = 47, and mC = 63, what is the measure of F? A. 63 B. 70 C. 47 D. Cannot be determined

I'm assuming that the full statement is ΔABC is congruent to ΔDEF.

Given:

m∠A = 70

m∠B = 47

m∠C = 63

Since both triangles are congruent, the corresponding angles in ΔDEF also has the same measure as those in ΔABC.

m∠D = 70

m∠E = 47

m∠F = 63

The measure of angle F is 63.
