Question

I don’t understand??

Answer 1

`\huge\boxed{\sf x = 10}`

Explanation:

Hypotenuse = x

Base = 4

Perpendicular =
`√(84)`

Using Pythagoras Theorem:

`\sf H^2 = P^2 + B^2\\\\ x^2 = (√(84) )^2 + (4)^2\\\\x^2 = 84 + 16\\\\x^2 = 100\\\\Taking \ sq \ root \ on \ both \ sides\\\\x = 10\\\\\rule[225]{225}{2}`

Hope this helped!
