Solve the equation 4 sin (x +30°) = 2 for 0 < x < 365

tatuchka [14]

$4 \sin(x + 30) = 2 \\ \sin(x + 30 ) = \frac{2}{4} \\ \sin(x + 30) = \frac{1}{2} \\ \sin(x + 30) = \sin(30) \\ x + 30 = 30 \\ x = 30 - 30 \\ x = 0$

Hence, x = 0°, 180° and 360° Ans

Solve for x. 2x + 16 = 3(x - 9) A) -43 B) -25 C) 0 D) 43

sergiy2304 [10]

Answer:

x = 43

Step-by-step explanation:

2x + 16 = 3(x - 9)

2x + 16 = 3x - 27

2x - 16 = 3x -27 (-16)

2x = 3x -43

2x (-3x) = -43

-1x or -x

-x = -43

-43/ -x = 43
