Answer:

Step-by-step explanation:
We want to solve the equation:

In the interval [0, 2π).
Notice that this is in quadratic form. Namely, by letting u = sin(θ), we acquire:

Factor:

By the Zero Product Property:

Solve for each case:

Back-substitute:

Use the Unit Circle. Hence, our three solutions in the interval [0, 2π) are:

Answer:
8
Step-by-step explanation:.25 is lower than .5
Answer:225
Step-by-step explanation:
Solving equations simple
9n + 12 = 30
K= -3
3y = x+6 can be rewritten as y = 1/3x + 2
a perpendicular slope is the opposite reciprocal of the original slope
so instead of 1/3 it would be -3
therefore. k must equal -3 to be perpendicular to 3y = x+6
