Start at one of the vertices and draw a line from there to a point on the oposite side, not ending at another vertex
If we know that 128 is 74% of something, we can write it like this:
74%x=128.
If we take the percent away (percent means by hundred in latin, 1%=1/100), we'll have
74/100 *x=128
//let's multiply both sides by 100, that way we can get rid of the ugly "/100 because 100/100 = 1, and we can ignore 1 in multiplications
100*74/100 *x = 128 *100// let's simplify the left side: 100/100=1
74*x=128*100// let's calculate the right side now
74*x=12800// now we have to divide both sides by 74
x=12800/74
if we divde this, we have: 172 + 72/74. (why? see below)
We can simplify the fraction by division by 2: 172 36/37

Answer:
It may be A. or C.
Step-by-step explanation:
A. 5 = 20 4 = 16 4 = 16 20 + 16 = 36 + 16 = 52
B. 3 = 12 3 = 12 7 = 27 + 12 = 39 + 12 = 51
i uhhh don't know this is confusing
im very sorry if im incorrect
Answer:
20. J, 21. B
Step-by-step explanation:
20. P = 15 (2) + 8 (2)
P = 36 ft.
21. 15 - 6 = 9 ft.
It's 60 m because 2 cm is 20 mm, and if each mm is 3 m then 20*3 is 60
