PLEASE HELP ME I have been asking for over 2 weeks just help!! What is this and how did you get the answer. I can’t find the perfect square.

Answer:
x=17
Step-by-step explanation:
Pythagoras theory
a^2 +B^2=c^2
15^2+8^2=C^2
225+64=C^2
[tex]\sqrt{289}[/tex]=C
C=17
Answer:
17 cm
Step-by-step explanation:
1. To solve this this problem, we can use the formula of the Pythagorean Theorem: [tex]a^2 + b^2 = c^2[/tex]
2. (Solving)
Step 1: Plug in values.
Step 2: Simplify both sides of the equation.
Step 3: Take square root of both sides.
Step 4: Check if solution is correct.
Therefore, x = 17 cm.
