Answer:
a=43
b=19.30263678
c=26.39302534
Explanation:
a=90-47
since it is a right triangle and has a right angle, the other two angles add up to 90 degrees
b=
tan= opposite leg/adjacent leg
tan 47= b/16 (cross multiply)
b=16*tan47

c=
cos= adjacent leg/hypothenuse
cos 47= 18/c (cross multiply)
c=18/cos 47
