Tan 120= 4000/x     (multiply each side of the equation by x)

x Tan 120=4000       (divide each side by Tan 120 )

x Tan 120/ Tan 120 =4000/ Tan 120

x=4000/ Tan 120

x= 18818.52 ft

Tan 100= 50/x     (multiply each side of the equation by x)

x Tan 100=50       (divide each side by Tan 120 )

x Tan 100/ Tan 100 =500/ Tan 100

x=500/ Tan 100

x= 283.56 ft

Sin x = 15/85

Sin x =0.1765       (Find the sin inverse of 0.1765)

x= Sin—1 0.1765

x= 10.160

32.

CAH

Cos x = 10/30

cos x =0.3333       (Find the cos inverse of 0.1765)

x= Cos—1 0.3333

x= 70.530

CAH

Cos 170= 20/x     (multiply each side of the equation by x)

x Cos 170=20       (divide each side by Cos 170 )

x Cos 170/ Cos 170 =20/ Cos 170

x=20/ Cos 100

x= 20.91ft

Rafter= x + overhang

Rafter= 20.91 + 1     (12 inch= 1 foot)

Rafter= 21.91 feet

34.

Sin 140= x/25 (multiply each side by 25)

25 Sin 140= x

x= 6.05 feet

35.

Cos 180= x/ 38 (multiply each side by 38)

38 Cos 180= x

x= 36.14 inches
