Answer:
The height of the cloud cover is 441.66 meters
Step-by-step explanation:
Distance = 560 m
The height of the cloud cover = h meters
According to the diagram, the worker stands at point R,
Let RT = x
tan 45⁰ =
= ![\frac{h}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7Bx%7D)
therefore, 1 =
, h = x
Then tan 75⁰ =
, substituting x = h, we have
3.732 = ![\frac{h}{560-h}](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B560-h%7D)
3.732(560 - h) = h
3.732 × 560 = 3.732h + h
2089.92 = 4.732h
h = 441.66 m
Answer: y-m2+m3=60(x+360) simplify y-m5=60x+60 scoot m5 over by adding it so y=60x+60=m5
PS: im sorry if im wrong :p
From the number 842 to 109 is a decrease of 733. so 109 minus 733 will result in a -624.
Answer:
5:5 or 7:3
Step-by-step explanation:
Step-by-step explanation:
If there are 15 red marbles, there'll be 7 blue marbles.
If there are 7 blue marbles, there'll be 3 green marbles.
If we get 2 blue marbles and put 2 green, than things will stay like this:
If there are 5 blue marbles, there'll be 5 green marbles.
If we get 2 green marbles and put 2 green, than things will stay like this:
If there are 7 blue marbles, there'll be 3 green marbles.
Answer:
h=7ft
Step-by-step explanation:
sinФ=opposite/hypotenuse
sin45°=5/h
0.71=5/h
multiply via by h
0.71h=(5/h)h
h cancel h it remains 5
0.71h=5
divide through by 0.71
0.71h/0.71=5/0.71
h=7.04ft
h=7ft approximately
