T + k = 1655
k = t + 239
now we sub
t + t + 239 = 1655
2t + 239 = 1655
2t = 1655 - 239
2t = 1416
t = 1416/2
t = 708 ft <== terminal tower
k = t + 239
k = 708 + 239
k = 947 ft <=== key tower
Since its multiplication you don't have to have a common denominator so you multiply straight across. The answer is 48/36.
The Alternate Interior Angle theorem states that when the lines are parallel, the alternate interior angles are equal. Since lines AB and CD are parallel, m∠ACD and m∠BAC are equal. So, the equation would be

or

.
Sin 2θ = sin θ
2sin θ cos θ = sin θ
2cos θ = 1
cos θ = 1/2
θ = arccos(1/2) = 60° and 300°
θ = 60° and 300°
He can receive 8 months of internet.
He has $134, and the initial fee is 30. Subtract 30 from 134. This gives you 104. Next, divide by the monthly fee of $13. 104/13=8
