Me i have 2 hours to answer this, at the very least give me the correct answer that's all i ask for, no explanation needed, i will give and ! :

83

Step-by-step explanation:

Order matters in:

Triangle JKL congruent to triangle MNP.

This says:

JK=MN

KL=NP

LJ=PM

So we need to find JK+KL+JL as a numerical value.

We also know from:

"Triangle JKL congruent to triangle MNP"

that angle K is congruent to angle N.

This means 20x-10=15x+15.

Add 10 on both sides:

20x=15x+25

Subtract 15x on both sides:

5x=25

Divide 5 on both sides:

x=25/5

x=5 .

JK=4x-4=4(5)-4=20-4=16.

KL=5x+1=5(5)+1=25+1=26.

So JK+KL+JK (which is just the sums of all the side measurements) is:

16+26+41

(16+26)+41

(42)      +41

42+41

83

So the perimeter of the pool is 83 ft.

83 goes in the blank.
