I am pretty sure the correct answer is $146.75. Hope this helps!!!!!!!
We can use Pythagorean's Theorem in order to find the remaining side length
a^2+b^2=c^2
Let a be the shadow length
Let b be the height of the flagpole
Let c be the hypotenuse
28^2+b^2=35^2
784+b^2=1225
b^2=1225-784
b^2=441
b=√441
b=21
Therefore the flagpole is 21 meters tall.
Hope this helps!
The answer is C because since the answer is 4 and if u look at c it would equal to 4.
Notice the picture below
x = 1 and y = -1
now... recall your SOH CAH TOA
now.. what's the value for "r" or the radius? well, using the pythagorean theorem
