Answer:
Step-by-step explanation:1.
Use law of cosine.
AB^2 = AC^2 + BC^2 - 2 * AC * BC * cos(angle ACB)
AB^2 = 53^2 + 71^2 - 2(53)(71)cos(53)
Using calculator,
AB = about 57.6259 feet
2.
Law of cosine again.
d^2 = 400^2 + 90^2 - 2(400)(90)cos(45)
using calculator,
d = about 342.3278 feet
The best choice would probably be the third option from the top. Since by using the distance formula you can solve for the length or distance of each of the sides of the triangle, and check to see if it is equal. As would be in an equilateral triangle.
Slope wouldn’t be best for the last leg or bottom leg as there is no change in y and x.
Answer:
50+=+%282w
50+=+2w
25+=+w
5+=+w
if width = 5 and l = 2w, then l = 10

Step-by-step explanation:
Let y represent the number of hours Maria works in a pay period.
Maria earns $5 per hour, then Maria earns
