Question

Question 10 (5 points) A 10-ft pole casts a shadow as shown in the figure. 6 to it (a) Express the angle of elevation of the sun as a function of the length s of the shadow. (b) Find the angle of elevation of the sun when the shadow is 15 ft long. (Round your answer to one decimal place.) Ω Format B 1 U ...

Answer 1

`\tan (a)=(10)/(s)\rightarrow a=\arctan ((10)/(s))`

and if the length of the shadow is 15, we get

`a=\arctan ((10)/(15))=33.7^(\circ)`
