Answer:
9. x = 7
10. x = 12
Step-by-step explanation:
Assume the two lines are parallel.
9. The corresponding angles are congruent.
9x - 3 = 7x + 11
2x = 14
x = 7
10. The alternate interior angles are congruent.
5x - 20 = 2x + 16
3x = 36
x = 12
The other leg is 6 and the Hypotenuse is 6√2
because it's a 45 45 90 the legs equal and the Hypotenuse is square root 2 times leg
m = -1
m = (1 - 3) / (4-2)
m = -2/2
