Mathematics
1 answer:
Sergio039 [100]3 years ago
7 0

Step-by-step explanation:

A) 3x + 8 = 23

3x = 23 - 8

3x = 15

x = 15 / 3 = 5

B) 5x + 1 = 3x + 17

5x - 3x = 17 - 1

2x = 16

x = 16 /2 = 8

C) 4 (x+2) = 32

4x + 8 = 32

4x = 32 - 8

4x = 24

x = 24 / 4 = 6

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.
