The height of the pole is 6.50 meters
<h3>How to calculate the height?</h3>
To calculate the height of the pole, we will use of the following equivalent ratios.
By Pythagoras theorem, we have:

So, we have:

Hence, the height of the pole is 6.50 meters

3/6+1/6+1 2/3
Make 1 2/3 into an improper fraction:
5/3
Give them all common denominators by multiplying both sides of 5/3 by 2:
10/6
Then the question becomes:
3/6+1/6+10/6
Now you add the numerators and the denominator stays the same:
14/6
Now you can simplify by dividing both sides by 2:
7/3
Now you can make it a mixed number:
2 1/3
Hope this helps :)
First of all i think theres a mistakein the question;
i think it is sin θ =

and then sin 30° =

thus θ= 30°
D)300% because it is an increase so you'd do 240/80=3•100=300
