[@farhansadik5423]

Found two ways while looking at the thumbnail, either use c^2=a^2+b^2-2abcos(theta) and solve for theta, or do the easy way and solve using law of sine

[@OkelloFred-jt6ge]

Sir why is that you use sine not when finding short distance

[@lavenderachieng8154]

Enjoy the show 😅😅

[@SamKiplangat-nt5kk]

Thanks to you Sir..,

[@heriseasy211]

Sir at calculating area it took me straight to the answer after the second step so i didn't divide with 2 at finding area to go to the final answer the calculator that iam using is from phone.now question was how will i know am i still gonna divide with 2 if i have a significant calculator....i currently don't have a one that's why I'm using this one

[@user-wq7nd6ud8b]

1/2*acsinB 2 it's in the formula.e.g 1*7.2*11.5 sin 105.4=79.82709947/2 from the formula hope have tried

[@fatormaamadu345]

Absolutely right 👍

[@mercysakala-wl9kx]

What if you've been given 2sides with no angles in side it's cosine rule
