Question

Can someone please help me with this problem

Answer 1

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
