Answer 2

Take it this way:
ABC and XYZ is both congruent, which means sides A and X are the same, B and Y are the same, and C and Z are the same.

Answer 3

So what do you think the angle of B is?

Answer 4

75?

Answer 5

Yep! Cause B and Y are equivalent

Answer 6

Now, we know A and B are 40 and 75. What would C be?

Answer 7

65?
