Answer:
A. 
Step-by-step explanation:
So to get the area of a square, we need to find the length of one side.
We know the length of the larger square is a, so the area of the larger cube is 
We can find the length of a side of the smaller square by using pythagoreans theorem to find the hypotenuse of the triangle formed in the bottom left corner. The length of one side along the x axis is a - b, and the length of the other side, along the y-axis, is b.
We can plug it into pythagoreans theorem to get
(C represents the length of one side of the smaller square, and the hypotenuse of the triangle)

The area of the smaller triangle is C squared to the area of the smaller triangle is

To get the ratio of the smaller square in comparison to the larger square we divide the area of the smaller square by the area of the larger square.
So the ratio should be

.25+.10+.10+.05+.05=0.55
fraction:55/100
Answer:
A, 95.
Step-by-step explanation:
The answer is 95 because the square is at a curve at the bottom right, so you need to subtract that amount from the original area, which is 100. So the actual answer is 95, hope this helped!
Answer:
SOHCAHTOA.
Step-by-step explanation:
acronym is an abbreviation formed from the initial letters of other words and pronounced as a word
The acronym for sin cosine and tangent is
SOHCAHTOA
Sine =Opposite over Hypotenuse
Cosine= Adjacent over Hypotenuse
Tangent= Opposite over Adjacent
