The answer is D)
60
°
All angles in a triangle equal 180
°. Since these two triangles are the same, you just need to find the missing angle. 70+50 = 120
180 - 120 = 60
Hope this helps!

Angle B and Angle Y are equal and we already have A so:
angle B + angle A + angle C = 180
70 + 50 + angle C = 180
120 + angle C = 180
angle C = 60
Hope this helps :)

Given that ΔABC ≅ ΔDEF, m∠A = 70°, m∠B = 60°, m∠C = 50°,m∠D = (3x + 10)°, m∠E= (1/3y + 20)°, and m∠F = (z2 + 14)°, find the values of x and y.
