Question

Triangle PQR is congruent triangle XYZ study the triangles carefully and then find angles X and Y

Answer 1

Step-by-step explanation:

By congruency

angle

P = X

Q= Y

R. = Z

hence

angle X= 80°

and Y= 50°

Answer 2

Answer:

In ∆ABC,

∠ACD = ∠A + ∠B (Exterior angle property)

= 70∘ + 40∘

= 110∘

Hence, the measure of ∠ACD is 110∘.
