## tayler_miller 3 years ago GEOMETRY HELP PLEASE.

1. tayler_miller

PQRS, PR= 10X-30and QS= x + 420.find the value of x and the length of each diagonal

3. imranmeah91

what's true about PR and QS?

4. tayler_miller

i dont knpw

5. imranmeah91

they are equal

6. tayler_miller

oh okay

7. tayler_miller

so whatdo i have to do?

8. imranmeah91

set PR and QS equal to each other(their value)

9. tayler_miller

ok and thenwhat

10. imranmeah91

then solve for x

11. tayler_miller

i dont know how to

12. imranmeah91

let set them equal to each other 10x-30= x + 420

13. tayler_miller

yea i did that

14. imranmeah91

10x-30=x+420 +30 = +30 --------------- 10x =x+270

15. imranmeah91

once you find x, plug it in either PR or QS to find length of diagonal

16. studyopen101

x=50. plug it in to one of the diagonals

17. studyopen101

10x=x+450 9x=450 x=50

18. tayler_miller

ok thank you guys i think i get it

Assuming PQRS is a Rectangle

20. PaxPolaris

x=50 length of each diagonal is 470 units
