written answer in the picture
Answer:

Step-by-step explanation:
since sin theta = 3/4, opposite length = 3 units and hypotenuse length = 4 units
by pythagoras' theorem, adjacent length = 
thus cos theta = adjacent/hypotenuse = 
Answer:
H=25√3
Step-by-step explanation:
So you would use the 30°,60°,90° Triangle theorem to solve this problem
Since we are trying to find out the 60°, because the x is across from 60° we can assume that we are just going to plug in x√3.
Hopefully you understand, didn't really explain it that well...
The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.
<h3>Why should the second arc be centered at C?</h3>
The second arc should be centered at C because as it crosses passing through Line C, it is seen that it was not touching or intersecting AB and so one can say that it is parallel to it.
Looking at the other lines, we will see that they are all touching AB and are not running parallel to it.
Hence, The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.
