This question looks incomplete. I am just of grade 7 and we r not introduced to trigonometry. Except what it is in my Syncconnect class ( I study in Amity International School) but I didn't understand it. I checked this question on an app called photomath but it didn't show anything. You can download the app and you won't have to sacrifice points for difficult questions
