Answer:
15 cm
Step-by-step explanation:
Write out the formula: a^2 + b^2 = c^2
Plug in the numbers that you were given: a^2 + 6^2 = 16^2
Solve for the numbers that you were given: a^2 + 36 = 256
Subtract: - 36 = - 36
a^2 = 220
Then, you find your answer: a^2 = 220
The square root of 220 is 14.832396974191326. But you are going to round it and you get 15. So, the answer is 15 cm.
Hope this helps
