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.
First, you need to know what a complementary angles are.
They are two angles that add up to 90 degrees.
If the number multiplied by 2 is 90, just to 90/2.
This gives you 45

Answer:
A
Step-by-step explanation:
The formula that relates current, power and resistance is
![I=\sqrt{\frac{P}{R}}](https://tex.z-dn.net/?f=I%3D%5Csqrt%7B%5Cfrac%7BP%7D%7BR%7D%7D)
Where
I is the current (in amperes)
P is the power (in watts)
R is the resistance (in ohms)
We know P = 500 and R = 25, we plug them into the formula and solve for I:
![I=\sqrt{\frac{P}{R}}\\I=\sqrt{\frac{500}{25}}\\I=\sqrt{20}\\ I=4.47](https://tex.z-dn.net/?f=I%3D%5Csqrt%7B%5Cfrac%7BP%7D%7BR%7D%7D%5C%5CI%3D%5Csqrt%7B%5Cfrac%7B500%7D%7B25%7D%7D%5C%5CI%3D%5Csqrt%7B20%7D%5C%5C%20I%3D4.47)
Correct answer is 4.47 Amperes, or choice A.
