The building is 24 (whatever’s you want ex. Meters, Feet) high. Because 38.7=tan^-1(height/30). Or cos(38.7)=30/hypotenuse. Hypotenuse=30/cos(38.7
Answer:
A. 1/3x + 1/2y <= 4
2x + y <= 12
x >= 0
y >= 0
Step-by-step explanation:
Yes! The lengths of each side must be less than the sum of the other two lengths. It looks like this:
4+4>7
7+4>4
4+7>4
Answer:
-3
Step-by-step explanation:
To find slope you first need to pick to points where the line crosses a corner.
Slope=
I'm using the points (0,-2) and (-1,1). You can either count up and over for the slope or use the slope equation

y2=second y point
y1=first y point
x2=second x point
x1=first x point
Now you just solve
or -3
