Answer: d) x=17
Explanation:
So a triangle is labeled a b and c, and a squared + b squared is c squared (Pythagorean theorem. A is 1, and b is 4. So 1 +16 is 17. And since c is squared, you would have to find the square root of 17 to reverse that. But what is odd is that there is no option for that. So I would just go with 17, which is what your instructor would want
