Question

What is the value of x for these problems? Pls help I’m so desperate

Answer 1

First Question x =
`17√(2)` Second Question x = 36

Explanation:

First Question:

Since The triangle is isosceles,
`17^2 +17^2=x^2` (Pythagoras)

`x=17√(2)`

Second Question

This is half an equilateral triangle, so
`((1)/(2)x)^2+(18√(3))^2=x^2`

`(3)/(4)x^2=972`

`x^2=1296`

`x=36` (cannot be negative)
