Answer:

D. 63 degrees

Explanation:

We can use the Trigonometric ratio ‘Tan’ to get angle B (because you have all 3 lengths, you can use any ratio. I used tan because it didn’t make use of the decimal number).

TanB = opposite/adjacent
TanB = 4/2
TanB = 2
B = Tan^-1(2)
B = 63.43°

Your answer is D.

Please feel free to comment if you do not understand the use of ‘Tan^-1’

Step-by-step explanation:

Given that the mean of the numbers is 12

$mean = \frac{sum \: \: of \: observations}{total \: number \: of \: observations}$

so here

let's that one as x and another one as 2x since it is given that one is twice the other

Therefore we get

$mean = \frac{13 + x + 4 + 16 + 6 + 2x}{6}$

Given mean = 12

$12 = \frac{39 + 3x}{6}$

$72 = 39 + 3x$

$3x = 33$

$x = 11$

Hence it's 11 and 22

Janine has job offer sat two companies. One company offers a starting salary of 28,000 with a raise of 3,000 each year. The othe

28,000 +3,000= 31,000 +3,000 = 34,000 +3,000 = 37,000 +3,000 = 40,000 +3,000 = 43,000 + 3,000 = 46,000

36,000 +2,000= 38,000 +2,000 = 40,000 +2,000 = 42,000 +2,000 = 44,000 +2,000 = 46,000

THE SALARY WOULD BE 46,000
IT WOULD TAKE 6 YEARS

I hope i did that right
