what did you get show your work :=)

3. Nnesha

remember these ? $\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }$

4. hybrik

There are two ways to do this

5. hybrik

One as @Nnesha said, two: You can use the ratios for 45:45:90,

6. hybrik

With the 45:45:90 method, the legs would be the same size, and the hypothenuse would be the same length of the leg multiplied by $\sqrt{2}$

|dw:1437747137827:dw| hint: 45:45:90 triangle has two equal sides

9. hybrik

As I said @Nnesha

10. Nnesha

yep :=) ik

11. Nnesha

let us know what you get girl! :=)

12. hybrik

Y = 7, and X = Y*the square root of 2
