You have $135 and you want to give the money to 5 of your friends. You want each friend to have the same amount of money. How mu
Alexus [3.1K]

Given:

Total amount = $135

Total friends = 5

Each friend to have the same amount of money.

To find:

The money you will give each of your friends.

Solution:

We know that,

\text{Money for each friend}=\dfrac{\text{Total money}}{\text{Total number of friends}}

Substituting the given values, we get

\text{Money for each friend}=\dfrac{135}{5}

\text{Money for each friend}=27

Therefore, each friend will get $27.

Need help solving the equation, trying to figure whether I multiply or divide.​
USPshnik [31]

Answer:

m∠B = 43°

b = 26.1

c = 38.3

Step-by-step explanation:

By applying triangle sum in the given triangle,

47° + 90° + m∠B = 180°

137° + m∠B = 180°

m∠B = 43°

By applying sine ratio to the angle measuring 47°.

sin(47°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

            = \frac{28}{c}

c = \frac{28}{\text{sin}(47^{\circ})}

c = 38.28

c ≈ 38.3

By applying cosine rule,

cos(47°) = \frac{\text{Adjacent side}}{\text{Hypotenuse}}

             = \frac{b}{c}

             = \frac{b}{38.3}

b = 38.3[cos(47°)]

b = 26.1
