Find the area of the triangles and smal ler square and add them together ; and find the area of the complete square and set them equal to each other (these are known truths)
triangle: l×w /2
square: s^2
There are 4 triangles so
4 (1/2ab)+c^2= (a+b)(a+b)
simplify
2ab+c^2= a^2+2ab+b^2
-2ab both sides
c^2=a^2+b^2
tada!! it's proven :)

Answer:
x = 8.0 m
Step-by-step explanation:
With the angle presented, I'm assuming you know basic trigonometry. We know cosθ = adj/hyp from SOH CAH TOA. We have angle and hypotenuse, so plugging in those values we get cos(20°) = x / 8.5. Solve for x to get 8.5cos(20°) = 7.987387277 m = 8.0 m.

Answer:
(D)$2079.23
Step-by-step explanation:
If I borrowed $11,250 from the bank to buy a used car. You will pay the bank back in 5 years with 3.45% interest compounded annually, then:
Principal=$11,250
Time=5 years
Rate=3.45%
Since it is compounded annually, our compound interest will be derived using this formula:
Interest=Amount at the end of 5 years - Principal
where:
Amount, 

Therefore our Interest=13329.23-11250 =$2079.23
