Answer:
sin(θ) = (2/5)√6
Step-by-step explanation:
The sine and cosine are related by the formula ...
Filling in the given value for cos(θ), we find the sine to be ...
__
The cosine function is positive for angles in both the first and fourth quadrants. The restriction on θ tells us this is a first-quadrant angle. The sine is positive in the first quadrant, so the desired value is ...
sin(θ) = (2/5)√6
Song is Never Gonna Give You Up
the figure is a pyramid and the area is 21
M = # of math problems
4/5m + 3 = 43
4/5m = 43 - 3
4/5m = 40
m = 40 * 5/4
m = 200/4
m = 50 <===there were 50 math problems
