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:
3.Area=πr²
d=14ft
r=7 ft
22/7*7*7
area=154ft²
5.area =1/2 bh
h=13cm
area=32.5cm²
32.5=1/2*13*b
32.5=13/2b
=5.0 or 5
base=5cm

Answer:
b. 21
Step-by-step explanation:
The first five mutiples of 7 are:<em> 7, 14, 21, 28, 35. </em>You can get these by multiplying 7 to any integer.
- 7x1 = 7
- 7x2 = 14
- 7x3 = 21
- 7x4 = 28
- 7x5 = 35
In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.
Let's add first.
7+14+21+28+35 = 105
Let's divided 105 by 5, which is the number of the multiples of 7.
105÷5 = 21
<em>The answer is 21.</em>
Ik this is not what you were looking for but what kind of problem is this lol. i never seen this
