need help which one is it
a)x=7
b)x=12
c)x=20

- you can use the pythagorean theorem for this.
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
- square root this.
c = 20
therefore, x = 20.
so option C.
Answer:
c. X = 20
Step-by-step explanation:
Pythagoras theorem
a² + b² = c²
12² = 144
16² = 256
144 + 256 = 400
√400 = 20
