Consider a right triangle in which one of the angles 
satisfies
That is, the side opposite occurs in a ratio of 3 to 5 with the hypotenuse. The side adjacent to then occurs in a ratio of 4 to 5 with the hypotenuse. In other words,
because
Then in this triangle,
-2x-y=3 ...(1)
x+2y=4 ...(2)
multiply (2) by 2 and add to (1)
-2x-y+2x+4y=3+8
3y=11
y=11/3
from (2)
x=4-2y=4-2(11/3)
or x=4-(22/3)
=(12-22)/3=-10/3
Sorry but I’m just commenting because apparently you have to answer other people’s questions in order to ask questions even when you have Brainley plus ugh
Answer:
I would say c and b
Step-by-step explanation:
I would say this because with out the number it would be that same thing and the same eqaution and formation
Area= Length x width
So....
Length= Area divided by width.
Plug in equation
20 divided by 5= L
L= 4
Answer is 4 cm
