Answer:
387 km
Step-by-step explanation:
The length of AC, b can be obtained using the cosine rule ; using the cosine relation:
b² = a² + c² - 2ac CosB
b² = 250² + 185² - 2(250*185) Cos125
b² = 62500 + 34225 - 92500 * −0.573576
b² = 96725 + 53055.820
b² = 149780.82
b = sqrt(149780.82)
b = 387.01527
b = 387 km (nearest whole number)
The answer is b
2cos x + 1 = 0
2 cos x = -1
cos x = -1/2
x = cos^1(-1/2)
(cos inverse (-1/2))
x = 120°

Answer:
Charlotte spent
on furniture
Step-by-step explanation:
Given:
Charlotte spent 25% more on furniture than she will on flooring
To Find:
Amount spent on furniture = ?
Solution:
Let the amount spent on flooring be x
and the amount spent on furniture be y
25% more on furniture than she spent on flooring can be written as
=>25% of x
So the cost spent on furniture will be
=>y= cost spent on flooring + 25% of cost spent on flooring
=>y= x + 25% of x
=>y=
=> y=
