Answer:
the first one is x=3
Step-by-step explanation:
The height of a building is 58.08 meters if the angle is 71 degree and the distance between A and B is 20 meters.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
Angle = 71 degree
Distance between A and B = 20 meters
Let's suppose the height of the building is x meters.
From the right angle triangle applying the tan ratio:
tan71 = x/20
x = 58.08 meter
Thus, the height of a building is 58.08 meters if the angle is 71 degree and the distance between A and B is 20 meters.

X = 8/(-1/3) therefore the answer is -24
Let's look at our equation,
<span>p÷7
We must look at all our options before selecting one of them.
Can the answer be A?
</span><span>Jayna does not know how many pages she needs to read. She knows she has already read for 7 days.
</span><span>
No that would not work,
We would have subtraction. It would look like this.
p-7.
How about B?
</span><span>Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span><span>
That would actually work. This is how our equation would look.
p</span>÷7.
<span>It matches the expression.
Before we make that our final answer, we should check everything else.
Here is C
</span><span>C.
Jayna does not know how many days she has to finish reading. She knows she has to read 7 more pages.
</span>
That would not work.
How about D?
<span>D.
Jayna does not know how many pages she has already read. She knows she has to read 7 more.
</span>
D is also incorrect. It would not work at all.
That means our final answer is:
<span>B.
Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span>
I hope that helped! :)
