Answer: A. Use Pythagorean Theorem to prove that KL is equal to c.
=========================================================
Explanation:
If we could show that KL = c, then we can tie together the following pairs of segments
- EG = KM = a
- GF = ML = b
- EF = KL = c
Then we'd use the SSS congruence theorem to prove the triangles are congruent. The last step is to use CPCTC to conclude that angle EGF is a 90 degree angle.
Keep in mind that we need to know the actual numeric values of 'a' and 'b' to be able to determine the value for c. So without the numbers, the Pythagorean theorem isn't really useful; however, I can see where your teacher is going with this line of logic. Your teacher is effectively just laying out a basic outline more or less.

Notes:
- SSS = side side side
- CPCTC = corresponding parts of congruent triangles are congruent
Use the formula for the volume of a cylinder to work out how much wax you need to make one candle.
π×5²×15 = 375π
Then divide the amount of wax you have by the amount of wax you need to produce one candle to work out how many candles you can make.
4500 ÷ 375π = 3.82
However, you can't produce 82% of a candle, so you have to round down to 3 candles.
Step-by-step explanation:
The product 1/8 times 8 to the square root
0.1 0.2 because its only sum of only 0.3
