L x w = 18
1 x 18 = 18
2 x 9 = 18
3 x 6 = 18
18 x 1 = 18
9 x 2 = 18
6 x 3 = 18
length can be 1, 2, 3, 6, 9, 18
width can be 1, 2, 3, 6, 9, 18
there are 6 possible lengths and widths
Answer:
(3,0) and (-9,0)
Step-by-step explanation:
Answer:
5. 6.1 units
6. 29.4 units
7. 12.8 units
8. 29.1 units
Step-by-step explanation:
5. We have the opposite and adjacent sides here for angle 21 degrees. So we need to use tangent, which is opposite / adjacent:

≈ 6.1 units
6. We have the opposite and hypotenuse sides here for angle 33 degrees. So we need to use sine, which is opposite / hypotenuse:

≈ 29.4 units
7. We have the opposite and adjacent sides here for angle 37 degrees. So we need to use tangent, which is opposite / adjacent:

≈ 12.8 units
8. We have the opposite and hypotenuse sides here for angle 31 degrees. So we need to use sine, which is opposite / hypotenuse:

≈ 29.1 units
Hope this helps!
