Given ∆ABC≅∆PQR,m (angle)B=3v+4,and m(angle)Q=8v-6,find m(angle)B and m(angle)Q

(quick question: what would be the symbol for "angle" on here?)

How do I solve this????
STEP-BY-STEP would be amazing! Thank you.

If the triangles are congruent, the corresponding angles are equal. So,

m∠B = m∠Q
3v+4 = 8v-6
v = 2

So, m∠B = m∠Q = 10°
