Let the distance from the engineer to the base of the building be x, then
tan 22 = 450/x
x = 450/tan 22 = 1,113.79
Therefore the distance from the engineer to the base of the building to the nearest foot = 1,114 feet
Answer:
The gradient is the same as the slope. To find the slope, let's convert this from standard form to slope-intercept form.
4x - 3y + 5 = 0
4x + 5 = 3y
4/3x + 5/3 = y therefore the answer is 4/3.
The area of the entire sector is 
The area of the triangle OAB is
.
So, the area of the segment is 
16 vegetables because 75-68=7 and 80-71=9 and 9+7=16
So basically what you have to do is
