Question

PLEASE HELP I GIVE THANKS

Answer 1

Pathagreom therom a^2+b^2=c^2 where c is the hypotenuse, or the longest side

so you have (8)^2 + z^2 = (17)^2

so 64 + z^2 = 289

next subtract 64 from the left and right side of the equation
64 + z^2 = 289
-64 -64

z^2=225
then take the square root and you get z=15

Answer 2

For any triangle problem with finding a length, use the Pythagorean theorem;
`a^(2) + b^(2) = c^(2)`
x=17cm, y=8cm
17²+8²=z²
289+64=z²
353=z²
√353=√(z²)
√353=z
The answer is D: √353 cm
