Answer 1

`a=8 ,b=6 ,c=35 ,d=37 ,e=15 ,f=17 ,x=32 ,y=65 ,z=25`

Explanation:

`Sin(x)=(opposite side)/(hypotenuse) \\Cos(x)=(adjacent side)/(hypotenuse) \\Tan(x)=(opposite side)/(adjacent side)`

x is in degrees.

14.

`Sin(37)=(b)/(10) \\\\b=10Sin(37)=6\\\\Cos(37)=(a)/(10)\\ a=10Cos(37)=8`

15.

`Cos(71)=(12)/(d)\\ d=12Sec(71)=36.858641...\\Tan(71)=(c)/(12) \\c=12Tan(71)=34.85053056..`

16.

`Tan(28)=(8)/(e) \\e=8Cot(28)=15.04581176..\\Sin(28)=(8)/(f) \\f=8Cosec(28)=17.04043576..`

17.

`Tanx=(28)/(45)\\ x=Tan^-((28)/(45))=31.89079...\\`

18.

`Cos(y)=(77)/(85) \\y=Cos^-((77)/(85))=25.05761..\\ z=90-y=64.94239...`
