Question 866731: A man has a 90ft ladder and leans the end of it against an exterior wondow of a house. The base of the ladder is 45ft from the house. Calculate to the nearest foot how high it is from window to the ground. the The formula i had to use was a^2 + b^2 = c^2
so c = 90, and a = 45 I am solving for b.
this is what I did but I don't think it is correct because the final answer is not an even square.
45^2 + b^2 = 90^2
2025 + b^2 = 8100
-2025 to both sides
b^2 = 6075
b is supposed to equal the square root of 6075
But I get 77.94228634
I don't think this is correct.

Question 871241: The total question is the following:
Graph the inequalities 9x+8y<72 and -7x-4y<=28 to find their solution set. Also, find their point of intersection. I also had to choose a graphing method for 9x+8y<72. I found the slope to be -9/8 with the y intercept being 0, 9. I then had to find a graphing method for -7x-4y<=28. I found that the slope was -7/4 and the y-intercept was 0,-7. I am unable to find the x and y coordinates of the intersection points.
