Please help! Thank you!

First one  ....Note that

sin L  = 21/75  ⇒    sin^-1 (21/75)   = L

cos L  = 72/75 ⇒  cos-1 (72/75)  = L

tan L = 21/72  ⇒  tan-1 (21/72) = L

Second one

sin A  = 35/37

cos A  = 12/37

tangent P  =   opp/adj =  24/18

tangent Q  = adj/opp = 18/24

tan 26/10

tan B  = 10/26

Note...on this silly  question.......one leg of the right triangle is LONGER than the hypotenuse...IMPOSSIBLE!!!!

Last one   .....we can use the tangent here 

tan 19  =   height  / 4100     multiply both sides by  4100

4100 * tan 19   = height  ≈   1412 ft

Remember So/h Ca/h To/a for the first one
