Answer:
The length of the legs of the triangle is 8 units.
Step-by-step explanation:
45-45-90 triangle
A 45-45-90 triangle is a special case of a right triangle in which both legs l have the same value and the hypothenuse is h. By the Pythagorean Theorem:
![2l^2 = h^2](https://tex.z-dn.net/?f=2l%5E2%20%3D%20h%5E2)
Hypothenuse of 8 V2
This means that ![h = 8\sqrt{2}](https://tex.z-dn.net/?f=h%20%3D%208%5Csqrt%7B2%7D)
So
![2l^2 = h^2](https://tex.z-dn.net/?f=2l%5E2%20%3D%20h%5E2)
![2l^2 = (8\sqrt{2})^2](https://tex.z-dn.net/?f=2l%5E2%20%3D%20%288%5Csqrt%7B2%7D%29%5E2)
![2l^2 = 64*2](https://tex.z-dn.net/?f=2l%5E2%20%3D%2064%2A2)
![l^2 = 64](https://tex.z-dn.net/?f=l%5E2%20%3D%2064)
![l = \sqrt{64}](https://tex.z-dn.net/?f=l%20%3D%20%5Csqrt%7B64%7D)
![l = 8](https://tex.z-dn.net/?f=l%20%3D%208)
The length of the legs of the triangle is 8 units.
Answer:
B
Step-by-step explanation:
7x + 13 = 48
7x = 48 - 13
7x = 35
x = 35/7
x = 5
