Answer:

x = 97

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 65² + 72² = 4225 + 5184 = 9409 ( take the square root of both sides )

x = $\sqrt{9409}$ = 97

Solve the math problem

Anastasy [175]

Try 89 because a triangle adds up to 180. I think you have to do 23 +68 which is 91 then minus 91 from 180 which is 89

Which is the equation of a parabola with focus (0, 5) and directrix y= -5?

Alja [10]

As the focus is at (0,5) it will be symmetrical about the y axis and will open upwards

General formula is x^2 = 4ay where a is the y coordinate of the focus

So its y = x^2/5*4

y = 1/20 x^2
