Answer:
Draw and label a diagram!
htop of tower / 325 = tan 34°
hbottom of tower / 325 = tan 31°
height of tower = htop of tower + hbottom of tower
The presence of an imaginary root (such as 4i) requires the presence of the complement of that root (which is -4i). Thus, there are 3 roots total here.
Alright! We know that the total number of students is 100%. So, if 65% of the students brought a hot lunch, in order to find how many students brought a packed lunch you subtract it from 100%:
[100 - 65] = 35
So 35% of the students brought a packed lunch. Now, in order to find the fraction of students you simply put 35% of students over the total percent of students (100%)"
[35/100]
Then you simply:
[35/100] ⇒ [7/20]
The answer is 7/20ths of the students brought a packed lunch.
