Answer:
1
Step-by-step explanation:
Since we know that there are exactly 180 degrees in any triangle, and if each angle is equal to 45 degrees, we must add 45 to 45 and then subtract the result from 180 to find the 3rd angle. Since 45+45=90,we subtract 180-90 and get 90 degrees or a right angle.
Hello!
You can use the Pythagorean Theorem to solve this

c is the hypotenuse
a and b are the legs
Put in the values you know

Square the numbers

Subtract 2.25 from both sides

Take the square root of both sides
b = 0.8
The answer is 0.8km
Hope this helps!
<span>I did the 38 times pi and got 119.3805 then multiplied it by 11
To get 1313.1855
Then divided by 2=
656.59275
And divided by pi
208.9999
Then round up.</span>
