Find all solutions of sin x - sqrt(1 - 3sin^2 x) = 0

Aparallelogram has two side lengths of 5 units. three of its sides have equations y = 0, y = 2, y = 2x. find the equation of the fourth side.

This is my question~~ ( r ^ 4 - 2r ^ 3 - 23 r ^ 2 - 4r - 32)÷(r+4) ~~ i must use long division to solve it : / i was wondering if anyone world like to solve it. and if so, share step-by-step explanations! you! ❤

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer
