Answer 1

Sin A=0.6

Tan B = 1.3333

Cos C= 0.9231

Cos C= 0.3846

Explanation:

For sin A

Sin A= opposite/hypotenuse

Sin A= 3/5

Sin A=0.6

For Tan B

Tan B = opposite/adjacent

Tan B = 4/3

Tan B = 1.3333

For cos C

Cos C = adjacent/hypotenuse

Cos C= 12/13

Cos C= 0.9231

For Cos D

Cos D= adjacent/hypotenuse

Cos C = 5/13

Cos C= 0.3846
