Question

(19 POINTS) SHOW WORK!!

Answer 1

Answer:

Apply sine and cosine theorem:

sinA = BC/AC = 16/20 = 4/5

cosA = AB/AC = 12/20 = 3/5

tanA = sinA/cosA = (4/5)/(3/5) = 4/3

Hope this helps!

Answer 2

Answer:

sin 16/20 = 0.717

cos 12/20 =0.825

tan

Step-by-step explanation

A when you draw a line down you get 16 cause we are looking sin of A first

B inside the box when you draw a line up it point to 20

together you get  sin 16/20 = 0.717

for the cos it is A to b  in between them is the adj

which is 12

and a to c is 20 is the hypotenus

togther is cos 12/20 = 0.825
