If a right triangle has a hypotenuse of length 20 units and one leg of length 16 units, find the length of the other leg. A. 12
xxTIMURxx [149]

Answer:

12

Step-by-step explanation:

Use the Pythagorean theorem which is a^2 + b^2 = c^2

c is hypotenuse and a and b are the legs

we need to find a^2 so

a^2 + 16^2 = 20^2

a^22 + 256 = 400

then subtract 256 from 400

a^2 = 144

square root 144

= 12

Sladkaya [172]
B.
{x}^{2} + 10x + 25 - 2x - 10 - 24 = \\ x {}^{2} + 8x - 9 = \\ (x - 1)(x + 9)

C.
{x}^{2} + 4x +4 - 8x - 16 + 15 = \\ x {}^{2} - 4x + 3 = \\ (x - 3)(x - 1)
D.
2( {4x}^{2} - 4x + 1) - 18x + 9 + 4 = \\ 8x {}^{2} - 8x + 2 - 18x + 13 = \\ 8x {}^{2} - 26x + 15
