Answer:
10.53
Step-by-step explanation:
Given :
Height of building = 17m
John's eye level = 2 m
Total height (including eye level) = 17+2 = 19m
Angle of depression, θ = 61°
Let distance between John's friend and building = d
Using trigonometry :
Tan θ = opposite / Adjacent
Tan 61° = 19 / d
1.8040477 = 19 / d
d = 19 / 1.8040477
d = 10.53
Where .75 will be on a number line always varies depending on how far out your number line goes. the decimal .75 is also known as 3/4, so the easiest way to find out where 3/4 is on a number line is to divide you number line into 4 even sections. this can be difficult if you have an odd number,, but it will always work as long as you divide the length of your number line by 4 to find out where to make your even sections. below is an example on how this would work:
lets say this is your number line
-------------------------
that number line contains 24 dashes,, so if you take that number (which is the length of the number line) and divide it by 4 you will find where 3/4 is.
24 ÷ 4 = 6
this means that at every 6,, you add 1/4. on the number line it would look like the following:
------I------I------I------
1/4 2/4 3/4
this technique shows you where 3/4/0.75 is on your number line.

11 i'm pretty sure!!!!!!!!
Answer:
she has 1/3 of her stickers left.
7/18+5/18= 12/18, which dicided by 6 equals 2/3, therefore she only has 1/3 left.
Step-by-step explanation:
i divided by 6 because it is the biggest whole number that both 12 and 18 go into.
