Question

Find the exact length of the third side

Answer 1

8

Explanation:

We will the pythagorian theorem :

• let x be the third side
• x²+6²= 10²
• x²= 100-36
• x=
  `√(64)`
• x=8

Answer 2

b=8

Explanation:

We can use the Pythagorean theorem since this is a right triangle:

a^2+ b^2 = c^2 where a and b are the legs and c is the hypotenuse

a=6 and b = 10

6^2 + b ^2 = 10^2

36+ b^2 = 100

b^2 = 100-36

b^2 = 64

Taking the square root of each side

sqrt(b^2) = sqrt(64)

b = 8
