THANK YOU SO MUCH! :)))

Hi! I am so confused about the given and what is being asked, I don't know how to solve it. This topic is solving situational problems involving trigonometric identities. Your help would be a big one for me :) Thank you so much in advance!

I got confused at the problem, especially the given i=30. But the instructor told me it was a typographical error. Thank you so much for your help! <3

Thank you so much for helping me! ♥️♥️♥️ This means a lot to me! Thank you!

Hi, I'm currently a Grade 11 student and I need help for this question (Precalculus): If $\sum\limits_{i=1}^{50} f(i)=90$ and $\sum\limits_{i=30}^{50} g(i)=60$, what is the value of $\sum\limits_{i=1}^{50} (7 g(i)-f(i)+12)/(2)$? P.S. To those who could answer this, it would be a great help...
