Simplify each term.

Multiply 8 by 2.

23−1⋅16

Multiply −1 by 16.

23−16

Subtract 16 from 23.

Subtract 8 from 23.

What is the missing leg length of the hypotenuse 23 and the other leg is 11??

valentinak56 [21]

To find the 3rd side of a triangle, use the pythagorean theorem.
a^2 + b^2 = c^2

a = 11
b = ?
c = 23

11^2 + b^2 = 23^2
121 + b^2 = 529
b^2 = 408
b = √408 = 2 √102 = 20.199, 20.2, or 20

The answer can be any of those.
