Use inverse cosine here because you have the side adjacent to angle A and the hypotenuse. On your calculator, press the 2nd key then cosine to see this on your display 
then enter 8/17 to give you an angle measure of 62 degrees.

Step-by-step explanation:
<u>Equation of a LIne</u>
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.
This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.
Two parallel lines have equal values for the slopes. The equation of the line
x + 5y = 10
Can be rearranged in such a way we can find its slope. Let's solve it for y:
5y = -x + 10
The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:
Adding 7:
