Remark

You must use the sin law to find this.


\dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12}

Multiply through by 12

12 * \dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12} *12


\dfrac{12*sin(75)}{22} = \text{sin(x)}

0.5269 = sin(x)


Now you have to use the inverse of the sine function.

Use your calculator for that

2nd F

sin-1

(0.5269)

= 31.79 degrees. <<<<<< Answer.


There sometimes is a second answer. I don't think there is in this case.

Answer:

(f + g)(3) = 9

Step-by-step explanation:

Given:

f(x) = x² + 1

g(x) = x - 4

Required:

(f + g)(3)

SOLUTION:

✔️Find f(3) by substituting x = 3 into f(x) = x² + 1:

f(3) = (3)² + 1 = 9 + 1

f(3) = 10

✔️Find g(3) by substituting x = 3 into g(x) = x - 4:

g(3) = 3 - 4

g(3) = -1

✔️Find (f + g)(3):

(f + g)(3) = f(3) + g(3)

= 10 + (-1)

= 10 - 1

(f + g)(3) = 9

22+(30-4) ÷2 And 18+(22-4) ÷6
schepotkina [342]

22 + (30 - 4) divided by 2

30 - 4 = 26

26/2 = 13

22 + 13 = 35

35

18 + (22 - 4) divided by 6

22 - 4 = 18

18 divided by 6 = 3

18 + 3 = 21

21
