<h3>(2-1) + 3² ÷ 3.</h3>
<em>To divide powers with the same base, subtract the exponent in the denominator from the exponent in the numerator. Subtract 1 from 2 to get 1.</em>
<h3>2 − 1 + 3¹</h3>
<em>Subtract 1 from 2 to get 1.</em>
<h3>1 + 3¹</h3>
<em>Calculates 3 to the power of 1 and gets 3.</em>
<h3>1 + 3</h3>
<em>Add 1 and 3 to get 4.</em>
<h3>4</h3>
The correct option is Alternative "C".

I'm not actually sure what your question really is, but I'll take a guess.
Before I go to work on that problem, let me ask you a few other questions:
-- If you have 2 cows and you subtract 4 cows, what do you end up with ?
-- If you have 2 rocks and you subtract 4 rocks, what do you end up with ?
-- If you have $2 in the bank and you subtract $4, what do you end up with ?
-- If you have 2 puppies and you subtract 4 puppies, what do you end up with ?
-- If you have 2x and you subtract 4x, what do you end up with ?
Did you say "negative 2 of them" for each question ? Good, good.
So now, if you have 2 ' y⁵ 's and you subtract 4 ' y⁵ 's, what do you suppose
you would end up with ?
I'm going to take your points and just let you think about that, because I think
I've given you all the help you need to answer the question on your own.
(That's if I actually understand <u>what</u> your question is.)
Answer:
d
Step-by-step explanation:

The <span>height of the tower. is 27 m
Now, we write h/x = tan 45
i.e h/x = 1
i.e h = x ...........................1.
Now, h/(x+20) = tan 30
i.e </span> (x+20)/h = 1/tan 30
or (x+20) = 1.73h
or from equation 1 ,
h+ 20 = 1.73 h
20 = 1.73h - h
h = 20/0.73
or h = 27.39 = 27 m
