The cosine of the angle is 4/5.
Step-by-step explanation:
An acute angle is between 0º and 90º, in the first quadrant of the trigonometric circle, in which both the sine and the cosine are positive values.
For each angle 
, we have that:
We have that:
So
The cosine of the angle is 4/5.
Answer:
There is not enough to solve.
Step-by-step explanation:
True - since the outlier is way off it will cause your average to mess up which is why we test multiple times to make sure we are more accurate with our numbers
Answer:
(x,y)=(0,0)
Step-by-step explanation:
Simplify -5x+3y=2x
2y=2x
multiply both sides -7x+3y=0
-x+y=0
