Sin(79)/17 = sin(x)/12

kondaur [170]

Answer:

44

Step-by-step explanation:

We want to solve the equation $\frac{\sin(79)}{17}=\frac{\sin(x)}{12}$

We multiply through by 12 to obtain:

$\sin(x)=\frac{\sin(79)}{17}*12$

We simplify the RHS to obtain:

$\sin(x)=0.6929$

This implies that:

$x=\sin^{-1}(0.6929)$

$x=43.86\degree$

To the nearest degree, x=44 degrees

We-haul rents a moving truck for $20.00 and $0.45 per mile. You-haul rents the same size moving truck for $1.00 per mile but wit

Verdich [7]

The two truck companies would cost the same amount at 36.36 miles.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total cost of rental for each truck for x mile.

From the table, for we-haul:

y = 0.45x + 20

For you-haul:

y = x

For the two trucks to cost the same:

0.45x + 20 = x

x = 36.36

The two truck companies would cost the same amount at 36.36 miles.
