Question

Given ∆ABC≅∆PQR, m<b =3v+1 and m<q= 6v-8, find m<b and <mq
10°
b.
26°
c.
11°
d.
29°

Answer 1

3v+1=6v-8
1+8=6v-3v
9=3v
9/3=v

Plug 3 into the expression to solve and you get 10.

Answer 2

If ∆ABC≅∆PQR, then m<b = m<q [ Corresponding sides ]

So, 3v+1 = 6v - 8
6v - 3v = 1 + 8
3v = 9
v = 3

Now, m<b & m<q = 3(3) + 1 = 9 + 1 = 10

In short, Your Answer would be Option A

Hope this helps!
