Can someone solve this for me?

Answer:
c = 11.66
Step-by-step explanation:
Pythagoras' Theorem states that ' the square on the hypotenuse of a right triangle is equal to the sum of the squares of the other 2 sides'
for this triangle it means that : c² = a² + b²
hence c² = 6² + 10² = 36 + 100 = 136
now c² = 136 ⇒ c = √136 ≈ 11.66
