Answer:

  745.5 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the trig function relating the hypotenuse and the side opposite an angle. It tells you ...

  Sin = Opposite/Hypotenuse

The line marked x (the hypotenuse of the triangle) is a transversal crossing the two parallel horizontal lines. That means the interior angle of the triangle at lower right (the angle of elevation) has the measure 28°. That angle is opposite the side marked 350 ft. So, you have ...

  sin(28°) = (350 ft)/x

Multiplying by x/sin(28°), this equation becomes ...

  x = 350 ft/sin(28°)

  x ≈ 745.5 ft

Evaluate the six trigonometric ratios for ø.
vova2212 [387]

Answer:

See below

Step-by-step explanation:

First off, the missing side is c=√(17²-8²)=15

sinø=opposite/hypotenuse=15/17

cosø=adjacent/hypotenuse=8/17

tanø=opposite/adjacent=15/8

cscø=hypotenuse/opposite=1/sinø=1/(15/17)=17/15

secø=hypotenuse/adjacent=1/cosø=1/(8/17)=17/8

cotø=adjacent/opposite=1/tanø=1/tanø=1/(15/8)=8/15
