Hope that helped :)
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)
ft
AB is the height of the house.
C.)
Since the ideal width is 7 cm and can vary by most 0.3 cm. This means the range is 6.7 cm to 7.3 cm Absolute value means that any negative number becomes positive. l 6.7 -7 l and l 7.3 - 7 l both equal 0.3 cm
l w - 7 l </= 0.3
i would pick number C) since i think it would be the correct answer
