Answer:
5 and -5 (±5)
Step-by-step explanation:
x²-8=17
x²=25
√x²=√25
x=±5
-126.....................................................
Assuming you have some angle measures, you could use the
Law of Sines to solve for the missing side lengths, which states that,

,
where a, b, and c correspond to the given sides you have, and A, B, and C represent the angles you have.
In this scenario, you would have to have the values for c (which we do), and have the angle measure of C. In addition, we would also need an angle measure that is either A or B.
Hope this helps a bit!

Answer:
a) 231
b) 52.8
Step-by-step explanation:
210*.10 = 21. 21+210 = 231
48*.10=4.8 4.8+48 =52.8
The length is 18 and it's width is 10 because 10+8=18 and 18•10=180
