By law of Sines:

c / sinC = b / sinB
33 / sin145 = 7 / sinB
sinB = sin145 * 7 / 33
sinB = 0.122
B = 6.99

How do I find the value of x for a pair of congruent triangles
Andreyy89
Hi there!

For congruent triangles, all angle measures and sides are congruent. So, if you look at the other triangle, and find the corresponding side, it will be the same measure.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
