Answer:
Explanation:
a) incorrect, sin= opposite/ hypotenuse
should be sinC=20.4/36.4
b)A= 180-90-34 = 56 so this is correct
c)incorrect, cos = adjacent/hypotenuse
should be cosC= 30.2/36.4
d) tanA =30.2/20.4
tan A = 1.48 so this is correct
e) this is correct, the side length just doubled, same answer
f)tanC = 20.4/30.2 =0.675
wrong rounded
