Answer:
A
Step-by-step explanation:
The angle on the right side of the triangle is 10° ( alternate angle )
Since the triangle is right with hypotenuse x use the sine ratio to solve for x
sin10° =
= ![\frac{200}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B200%7D%7Bx%7D)
Multiply both sides by x
x × sin10° = 200 ( divide both sides by sin10° )
x =

Answer:
18.75 ft
Step-by-step explanation:
The given scenario can be drawn as shown in the following attachment.
Given that,
and ![m\angle DEC=\angle ABC=90^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20DEC%3D%5Cangle%20ABC%3D90%5E%7B%5Ccirc%7D)
Therefore, ![\Delta ABC\sim \Delta DEC](https://tex.z-dn.net/?f=%5CDelta%20ABC%5Csim%20%5CDelta%20DEC)
![\Rightarrow \dfrac{AB}{DE}=\dfrac{BC}{EC}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7BAB%7D%7BDE%7D%3D%5Cdfrac%7BBC%7D%7BEC%7D)
![\Rightarrow \dfrac{AB}{5}=\dfrac{15}{4}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7BAB%7D%7B5%7D%3D%5Cdfrac%7B15%7D%7B4%7D)
