PLS HELP!!
Answers: 8,20,35,12

Answer 1

the answer is 8.

Explanation:

Use the Pythagoras Theorem since it is a triangle.

`a^(2)+b^(2)= c^(2)\\\\a^(2)+15^(2)= 17^(2)\\ a^(2)+225=289\\ a^(2)=289-225\\ a^(2)= 64\\ √(a)= √(64)\\ a=8`

Since you have the hypotenuse and base, just put those into the equation and find the missing side.
