Y2-y1/x2-x1. so -7-8/-1-(-1)= -15/1
Answer:
<u>135.94 feet</u>
Step-by-step explanation:
Split the problem into two parts :
- Distance between viewer and building
- Height of the top part of the building
<u>Distance between viewer and building</u>
- The lower part of the building is 40 feet, as it is mentioned the viewer is 40 feet above street level
- Let the distance be called 'd'
- Therefore, tan37° = 40/d
- tan37° = 3/4 = 0.75
- ⇒ 40/d = 0.75
- ⇒ d = 40/(3/4) = 40 x 4/3 = 160/3 = 53.3 feet
<u>Height of the top part of the building</u>
- Let the height of the top part be 'h'
- Therefore, tan61° = h/d = h/53.3
- tan61° = 1.8
- ⇒ h/53.3 = 1.8
- ⇒ h = 53.3 x 1.8 = 95.94 feet
<u>Total height of building</u>
- Lower part + Top part
- 40 + 95.94
- <u>135.94 feet</u>

Answer: False.
Step-by-step explanation:
48 is not a common factor of 4 and 6
4 and 6 only share 2 factor: 1 and 2
Factors in 4: 1, 2, 4
Factors in 6: 1, 2, 3, 6
we know that
<u>To Round a number
</u>
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than 
(this is called rounding down)
c) But increase it by 
if the next digit is or more (this is called rounding up)
In this problem we have
Round to the nearest 
We want to keep the digit 
The next digit is which is or more, so increase the digit by
therefore
<u>the answer is </u>
<span>So we want to know what is the sum of 6 feet 10 inches and 8 feet and 9 inches. To know that we need to know that there are 12 inches in one foot. So lets do the calculation. 6 feet + 8 feet = 14 feet. 10 inches +9 inches = 19 inches or 1 foot and 7 inches. We add 1 foot to our 14 feet and get the result: 15 feet 7 inches. </span>
