Find x. round to the nearest tenth.

21.4 degrees =x

Step-by-step explanation:

We can use the law of sines to solve this problem

sin A            Sin B

=

a                  b

where A is the angle and a is the opposite side

sin 42           Sin x

=

22                  12

Using cross products

12 sin 42 = 22 sin x

Divide by 22

12/22 sin 42 = 22/22 sin x

12/22 sin 42 =  sin x

Take the arcsin of each side

arcsin (12/22 sin 42) = arcsin( sin x)

arcsin (12/22 sin 42) =  x

21.40637223=x

Rounding to the nearest tenth

21.4 degrees =x

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

98%
