A^2 + b^2 = c^2
4^2 + b^2 = 5^2
16 + b^2 = 25. -16
B^2 = 9
Square root of 9 = 3
B = 3
The other leg is 3cm
3/8 is the correct answer
$15 interest to 2 years simplified would be $7.50 interest per year. $7.50 multiplied by 10 years would be $75 interest.
The formula of a perimeter of a rectangle:

We have:

Substitute

<h3>Answer: Length = 35 in, Width = 25 in.</h3>
Answer:

Step-by-step explanation:
- The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
- The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
- We can get the length of the longest side of the bottom triangle is 9×2÷√3 =

- And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is
x√2
