Question

Use the pythagorean theorem to find the value of x.​

Answer 1

6.9 cm

Explanation:

hyp² = adj² + opp²

Answer 2

x = 6.93 cm

Explanation:

Pythagorean theorem: c =
`√(a^2 + b^2)`

C is the hypothenuse, the longest side of a right angled triangle.

Here c = 8, 4 =a, b = x.

`8 = √((4)^2+(b)^2)`

`64 = (4)^2 + (b)^2`

`64 = 16 + (b)^2`

`b^2 = 48\\b = √(48) = 6.93 cm`
