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
Since we know a square has 4 equal sides
and is equal to to exact right triangles.
USing the formula for Perimeter
l+l+w+w=P or 2L+2W=P
56cm÷4=14 so now we have
(2)14+(2)14=P
P=14cm^2
The slant length on a triangle is equal to L
Slant lenght=14
First, do 36/12 to find out how many laps you can run in a certain amount of minutes. It is 1 laps per 3 minuted. Then, do 3 times 20 because 60 minutes is in an hour. Then, 1 times 20 is 20. 20 laps is the correct answer.
Answer:
$7.50
Step-by-step explanation:
4 x 3.00 = $12.00 3.00 off the regular price makes it 12.00 for all the banners
12.00 + 18.00 = 30.00 you add the sale price with the 12.00 to get the total of each banner before the store gave the sale price.
30.00 divide by 4 = 7.50 to find out what the regular price of the banner you divide by the total of banners you bought to get the price of each banner before the sale.
