Answer:

  • B. 630 ft

Step-by-step explanation:

<u>Given:</u>

  • Horizontal leg of the right triangle = 778 ft
  • Angle opposite to vertical length = 39°
  • Vertical leg = h

<u>Use tangent to solve for h:</u>

  • h/778 = tan 39°
  • h / 778 = 0.81
  • h = 0.81*778
  • h = 630.18

Correct choice is B

ANSWER:

On using trigonometric function, we get

tanΦ = p/b

tan39° = p/778

p = 778 × 0.81

p = 630ft rounded.

So, <u>Correct choice</u> - [B] 630 feet.
