Step-by-step explanation:

Step 1: Define

2x² = 50

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

x = 5

Here we see that 50 does indeed equal 50.

∴ x = 5 is a solution to the equation.

x = -5

Here we see that 50 does indeed equal 50.

∴ x = -5 is a solution to the equation.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
