If Anna and Tamara's travel time between Bonita Springs and Northville is 5x - 10, what is the travel time between the two when x = 45? (time is in minutes)
Minutes

Answer \frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

\frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}

which is the required equation for finding the value of x,

\frac{x}{sin40^{\circ}}= \frac{12}{sin60^{\circ}}

x= 12\times \frac{sin40^{\circ}}{sin60^{\circ}}

x= 12\times 0.74222719896

x= 8.90672638762\approx 8.967

=215

Explanation:

5x-10 subsitute  45 for X

=5(45)-10

simplify

=225-10

=215
