4x^2 + x + 3 = 0
x = [-1 +/- sqrt (1^2 - 4 * 4 * 3)] / 8 = - 1 +/- sqrt ( --47) / 8
= ( - 1 +/- sqrt47i) / 8 = -0.125 + 0.857i , -0.125 - 0.857i
Answer:
The answer to your question is x = 37.74
Step-by-step explanation:
Data
Right triangle
hypotenuse = c = 45
angle = 33°
adjacent side = x
Process
To solve this problem use trigonometric functions. The trigonometric function that relates the adjacent side and the hypotenuse is cosine.
cos Ф = Adjacent side / Hypotenuse
-Solve for Adjacent side
Adjacent side = hypotenuse x cosФ
-Substitution
Adjacent side = 45 x cos 33
-Simplification
Adjacent side = 45 x 0.839
-Result
Adjacent side = x = 37.74
