Solve the equation 4 sin (x +30°) = 2<br>for 0 &lt; x &lt; 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° <em><u>Ans</u></em>

Help find y .. slope is m=-5/8
goblinko [34]

y = 8

using the ' gradient formula' m = (y₂ - y₁)/(x₂ - x₁)

with (x₁, y₁) = (3, 3), (x₂, y₂) = (- 5, y) and m = - \frac{5}{8}

(y - 3)/( - 5 - 3) = - \frac{5}{8}

(y - 3)/(-8) = - \frac{5}{8}

multiply both sides by - 8 to eliminate fractions

y - 3 = 5

add 3 to both sides

y = 5 + 3 =8
