I need help finding x
BigorU [14]

Answer:

The answer to your question is      x = \sqrt{50}    or x = 5\sqrt{2}

Step-by-step explanation:

To solve this problem use the Pythagorean theorem because two right triangles are formed.

                    c² = a² + b²

c = 10

a = x

b = x     Because in a square all the sides measure the same.

                    10² = x² + x²

- Simplify

                    100 = 2x²

                    x² = 100/2

                   x² = 50

                    x = \sqrt{50}    or x = 5\sqrt{2}

14.4

Step-by-step explanation:

sin x = 24/30

x = sin^-1 (24/30) = 53.13

sin 53.13 = x/18

x = sin 53.13 x 18 = 14.4

The answer is C, but I don't understand why- can anyone tell me?
finlep [7]

Answer:

It's C because we are adding a number on the x but here we skip 5 so it's 6, and on y we add 4 up but since we skipped 5 we add 8 and we get 24. 6, 24. You may say "but SpiritBear, 17 plus eight is 25" and that is true, but if you notice the lowest dot actually starts on 5, not 4 making C right.

Hope this helped and wasn't too confusing
