You can use what is called a clinometer that measures angles. You can also use a digital level app on your phone. Hold it at eye level at 0 degrees and then tilt up or down until you see the object.
When more angles are given, it is typically the Sine Law, but not necessarily every time. I would always check to see if it fits the Cosine Law first. Look for all three sides (SSS) or a "sandwiched" angle, Side-Angle-Side, (SAS). If you do not see any of those it is likely you have to use Sine Law or you have to find additional information using angle properties.
Thanks for teaching me this is the best thing that I have not teach in my class 🙏🙏
Thanks for the help man i have a functions test tomorrow
You dont actually need sine rule for the first one, just use trig identities and solve for height with simultaneous equations
Thank you so much
How the hell does that girl eyeball the 17 degree angle? How do u measure that in real life?

Thanks, very helpful.

Excuse me sir, so basically we use the law of cosine if more sides are given. And the law of sine if more angles are given?

siempre que pienso que se mucho me doy cuenta de que no se casi nada
