Answer:
The angle  measures approximately
 measures approximately 
Step-by-step explanation:
Since this problem involves the finding of an angle in a right angle triangle for which we know the opposite side and the adjacent side, the trigonometric function that relates them is the tangent:

Then, for our case we get a starting equation that reads:

and for which we need to solve for  . Then we use the arctangent function to get the final answer:
. Then we use the arctangent function to get the final answer:

Answer:
(-4,9)
Step-by-step explanation:
substitute the given value for y into the first equation
x-5(-2x+1)=-49
distribute
x+10x-5=-49
add like terms
11x-5=-49
add 5 to both sides 
11x=-44
divide both sides by 11
x=-4
now plug x into into the second equation 
y=-2(-4)+1
y=8+1
add like terms 
y=9
