Answer:

B. 630 ft

Step-by-step explanation:

Given:

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

Use tangent to solve for h:

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

Correct choice is B

Figure CDEF is a parallelogram.

Salsk061 [2.6K]

We see that CF and DE are parallel to each other, which means that they had the same length with each other, so:
6n-1=5n+9
Subtract 5n for both side
6n-1-5n=5n+9-5n
n-1=9
Add 1 for both side
n-1+1=9+1
n=10
CF=
6n-1
=6(10)-1
=60-1
=59
DE=
5n+9
=5(10)+9
=50+9
=59
CD/FE:
4n+2
=4(10)+2
=42
True/False:
n=10 True
n=7 False
CF=59 True
FE=42 True
CD=30 False. As a result, n=10;CF=59; and FE=42 is your final answer. Hope it help!
