The largest triangle and the triangle whose hypotenuse is x are similar. So:

(21 + 4)/x = x/4

Cross multiply:

x^2 = 100

x = 10

Your answer is incorrect. It should be 10, not 20.

So since its a right triangle, we can use the pythagorean theorem, which is $leg^2+leg^2=hypotenuse^2$ . Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:

$2^2+3^2=x^2\\ 4+9=x^2\\ 13=x^2\\ \sqrt{13}=x$

Since √13 can't be further simplified, that is your final answer.

Find the difference between 4/11 of 2½ and 3/4

Lunna [17]

Answer:

4/11 of 2 1/2 = 4/11 * 5/2 = 20 / 22 = 10/11

a common denominator of 11 and 4 is 44

So 40 / 44 - 33 / 44 = 7/44

Check 4/11 * 2.5 = .909

3/4 = .75

difference = .909 - .750 = .159

7/44 = .159
