Answer:

a) 42

b) 23

F) 115

Step-by-step explanation:

First, find the angles that are missing in triangle CD1F. (D1 being the inside angle of the triangle)

D1 make a line with 157 and results in 180.

Therefore, 180 - 157 = 23

Now you can find F, 180 - 42 - 23 = 115

A and C are vertical opposites and have the same angle, so 42.

B = 180 - 115 - 42 = 23

Answer:

The length of the lights is 2088 inches

Step-by-step explanation:

<em>The question is mixed up with another (See comment for correct question)</em>

Given

$Length = 799in$

$Width = 245in$

Required

The perimeter of the deck (this is what the question implies)

The perimeter (P) is:

$P = 2 * (Length + Width)$

$P = 2 * (799 + 245)$

$P = 2 * 1044$

$P = 2088$
