Question

I don't get this...​

Answer 1

Hello!!! Princess Sakura here ^^

Explanation:

So first you should remember that....

`a^(2) +b^(2) =c^(2)`

then you should plug in...

`8^(2)+16^(2)`

that should equal...

`c^(2)=320`

Then you should solve the equation now by doing the inverse of the square which is the square root of both sides...

`\sqrt{c^(2) } =√(320)`

`c=17.88854382...`

Then you have to round it to the nearest tenths, which'll give you...

`17.9`

choice D

Answer 2

Answer: The answer is D. 17.9

Step-by-step explanation: Use the equation
`c = √(a^2 +b^2)` where c represents the triangles hypotenuse and a and b represent the legs of the triangle.

I hope this helps have a great day!
