Step-by-step explanation:
because it would have many solutions
Cos(angle) look at the 'x' axis, so cos(t)>0, means positive x, or quadrants I and IV.
tan(angle) = sin(angle)/cos(angle), so it's a division. sin(angle) has the sign of the y axis.
So, tan(t)>0, mus be +/+ or -/-, quadrant I or III, respectively.
The only in common is quadrant I. Hope it helps for the next one!
80% of what is 56
0.80x = 56
x = 56/0.80
x = 70
