Viktor [21]

Answer:

Step-by-step explanation:

Factor out to simplify:

15d+105=4d-16+11d

15d+105=15d-16

subtract 15d from both sides

105=-16

this means that there are no solutions for d

From the top of a tower, an object which is 97 m away from the base of the tower, is at a 37° angle of depression.

<h3>Answer:  73</h3>

==================================================

Work Shown:

Check out the diagram below. Note the pair of alternate interior angles that are congruent (each 37 degrees). Then focus on triangle ABC. With the reference angle being at A, this means we use the tangent function because BC = x is the opposite side and AB = 97 is the adjacent side.

tan(angle) = opposite/adjacent

tan(A) = BC/AB

tan(37) = x/97

97*tan(37) = x

x = 97*tan(37)

x = 73.094742859971

For the last step, you'll need a calculator that can handle trig functions. Make sure the calculator is in degree mode. The result here is approximate. This rounds to 73 when rounding to the nearest whole number.
