F=90
D=37
E=53
f=18.3
d=11
e=14.6
Step-by-step explanation:
Triangle Sum Theorem means 180-37-90=E. So, E=53 degrees.
Sin(37)=![\frac{11}{f}](/tpl/images/1159/7025/02a07.png)
fsin(37)=11
f=![\frac{11}{sin(37)}](/tpl/images/1159/7025/2f339.png)
f=18.3
Tan(37)=![\frac{11}{e}](/tpl/images/1159/7025/e284f.png)
etan(37)=11
e=![\frac{11}{tan37}](/tpl/images/1159/7025/d122d.png)
e=14.6
Make sure your calculator is in DEGREE mode.

30 people
Step-by-step explanation:
If you start off with 1/2 a lemon for 6 people, then 1 whole would be 12. 1 1/2 would be 18 people and 2 whole lemons would be 24. so 2 1/2 is 30 people.
