Answer:
B = 13
Step-by-step explanation:
The tangent and cotangent are equal when the angles are complementary.
(3B +35) +(2B -10) = 90
5B = 65
___
<em>Check</em>
For B=13, the angles are 3B+35 = 39+35 = 74, and 2B-10 = 26-10 = 16. Both are acute angles.
Yes, you are correct, if it is 37 minutes and you are supposed to round, you round up.
