Since this is a right triangle, you can use the pythagorean theorem:
(a^2+b^2=c^2)
your formula will be:
your hypotenuse will take the place of c. (8) and 6 will take the place of a.
simplify the squares:
subtract 36 from each side:
un-square the b by square rooting 28.
this will come out as a large # that's equal to:

1.
Step-by-step explanation:
4. 7x - 2 = 9x + 10
- 9x + 2 - 9x + 2
_____________
3. 4x + 8 = 3(x - 1) + 12
4x + 8 = 3x - 3 + 12
4x + 8 = 3x + 9
- 4x - 9 - 4x - 9
____________
2. 3x + 7 - 2x = 4x + 10
x + 7 = 4x + 10
- 4x - 7 - 4x - 7
____________
1. −2x + 8 = 2x + 4
- 2x - 8 - 2x - 8
