Send , inverse trigonometric functions

We know soh cah toa so all we need to do is answer as we normally do but with all little change

Going from b we know 150 is are opposite and 105.03 is adjacent so this would be tangent opposite/adjacent

150/105.03 = 1.428

Change is here now do inverse tangent to 1.428= 54.99 is the angle of b

Remember all were doing is finding the trig function like normal (dividing) then we just put that number in with the inverse trig function

To find angle c all we need to do is add 90+54.99 and subtracted that from 180 which means c is 35.01.
