Question

What is the length of the hypotenuse? If necessary, round to the nearest tenth.
c2=16+64

Answer 1

a^2 + b^2 = c^2 is the formula you use to find hypotenus
a=16 
b=64
16^2 + 64 ^2 = c^2 
256 + 4096 = c^2
4352 = c^2 
take square root of each side 
= 65 rounded to nearest 10th 
  

Answer 2

The hypotenuse is the longest side of a right triangle

The length of the hypotenuse is 8.9

The Pythagoras equation of the right triangle is given as:

c^2 = 16 + 64

Evaluate the sum

c^2 = 80

Take the square root of both sides

c = 8.9

Hence, the length of the hypotenuse is 8.9
