Answer:
The length is 81 feet.
Step-by-step explanation:
If you plot the equations for both length and width on a graph, making them both equal to y of course, you find that they cross each other in two places. The places they cross are (81, 11) and (70, 0). It is impossible for the answer to have the width as 0 feet, so the answer is 81 feet.
Answer:
660 m squared
Step-by-step explanation:
5 x 12 = 60
60 / 2 = 30
22 x 30 = 660
the volume is 660 m squared
Answer:
k = 45
The angles are 45 , 45, 90
Step-by-step explanation:
The sum of the angles of a triangle are 180
45+ k+2k = 180
Combine like terms
45+3k = 180
Subtract 45 from each side
45+3k-45 = 180-45
3k = 135
Divide by 3
3k/3 = 135/3
k =45
The angles are 45, k,2k
The angles are 45 , 45, 90
