Answer:
X Y
8 4
14 7
6 3
Step-by-step explanation:
y = x/2
x = 2y
I will get you started.
Let sin x = u
Then 7sin^2x -14sinx+2=-5 become
7u^2 - 14u = - 5
7u^2 - 14u + 5 = 0
Steps:
1. Solve for u.
2. Back- substitute for u.
3. Take the arcsin on both sides to find the angle(s).
You finish.
Easily done! Just do -56 divided by -7 but just remember two negatives equal a positive. So your answer would be 8!
