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.

Value of x is 20 and y is 120.

Step-by-step explanation:

Given,

m∠A = 70°, m∠B = 60°, m∠C = 50°,m∠D = (3x + 10)°, m∠E= (1/3y + 20)°, and m∠F = (z² + 14)°

Also,

ΔABC ≅ ΔDEF,

Since, the corresponding parts of congruent triangles are always congruent or equal.

⇒ m∠A = m∠D, m∠B = m∠E and m∠C = m∠F

When m∠A = m∠D

When, m∠B = m∠E,
