Answer:
That is a 45-45-90 triangle next to a 30-60-90 triangle.
So, the height of the left triangle equals 5.
That makes the short side of the 30-60-90 triangle also equal to 5.
In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.
Therefore, the hypotenuse (or "x") equals 10.

Answer:
A. 2/5, 0.40, 40%
Step-by-step explanation:
To turn a fractions into a decimal divided the numerator by the denominator. 2/5=0.40.
Answer:
10√3 feet
Step-by-step explanation:
In a 30-60-90 triangle;
-Long leg = long leg
-Short leg = 1/2 * long leg
-2nd longest leg = short leg * √3
-Long leg = 20
-Short leg = 1/2 * long leg = 10
-2nd longest leg = short leg * √3 = 10√3
1 1/4= 1*4+1 /4. Or 5/4
In order to subtract you must have same denominator. 5/4 -3/8
Multiply 5/4 times 2/2. =. 10/8. -3/8
The difference is 7/8
