It's a 45-45-90 triangle,
where the legs are congruent, and the hypotenuse is sqrt(2) times the length of a leg.
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.

Answer:
C.
Step-by-step explanation:
3 times 2 is 6, 2 times 5 is 10, 5 times 3 is 15. However you need 2 for each since there are 3 sets of two equal faces. So it will be 6+6+10+10+15+15
