Answer:
67.88°
Step-by-step explanation:
If three sides of a triangle are known and you want to determine one angle, this can be done using cosine rule.
Given sides x, y, and z and the angle Y is opposite to side y, the cosine formula is given as:
y² = x² + z² - 2xzcosY
For this problem, x = 400 miles, y = 599 miles, z = 320 miles.
Using the cosine formula:
Degree to adjust its route at point Y = 180° - 112.12° = 67.88°
It needs to adjust by 67.88° at point Y
Answer: 14 seed packs
Step-by-step explanation:
You'd divide the 9 tomatoes by the 6 seed packs that were necessary to grow them, resulting in 1.5 tomatoes per seed pack. Divide 21 by this 1.5 to find the number of seed packs needed to grow 21 tomatoes, which would be 14.
6x+4x-6=24+9x
10x-6=24+9x
1x-6=24
1x=30
x=30
