Answer: 18
Step-by-step explanation: Angles opposite of each other in a trapezoid equal 180 minus each other so 180 - 105 = 75 so 75 = 4y + 3
Subtract 3 from both sides
72 = 4y
Divide by 4
y = 18
Sqrt14 = 3.74 (2dp)
The principal root is always the positive.
The answer is 1761 1/2 (1761.5 in decimal form)
12 x .75 = 9 ft (horizontal)
4 x 1.5 = 6 ft (vertical)
