A carpenter charges $325 for 13 hours of work. She charges the same amount of money for each hour of work.
Citrus2011 [14]

Answer: She charges 25 dollars per hour.

In triangle abc, if A=120 degrees, a=8 and b=3, then angle B=
CaHeK987 [17]

The angle of B is \angle B=19^{\circ}

Explanation:

It is given that \angle A=120^{\circ} and a=8, b=3

To determine the \angle B, let us use the law of sine formula.

Thus, we have,

\frac{Sin A}{a} =\frac{Sin B}{b}

Substituting the values in the formula, we have,

\frac{Sin 120}{8} =\frac{Sin B}{3}

Multiplying both sides by 3,we get,

\frac{3(0.866)}{8} ={Sin B}

Simplifying and dividing, we get,

0.32475=Sin B

Multiplying both sides by \sin ^{-1}, we get,

\sin ^{-1}(0.32475)=B

Thus, B=18.95^{\circ}=19^{\circ}

Hence, The angle of B is \angle B=19^{\circ}
