Answer:
x = 18
Step-by-step explanation:
Since both right triangles are similar, therefore:

Cross multiply




Subtract 780 from both sides





x + 23 = 0
x = -23
Or
2x - 36 = 0
2x = 36
x = 18
40 divided by 45 equals about 0.89
so its 89%

l*w*h= volume
Answer: 24 inches
Step-by-step explanation:
First, remember that 1 ft is equal to 12 in
Then, if 1 ft = 12 in
1 = 12in/1ft
this means that we can write a constant:
C = 12in/1 in
and C = 1, then we can write the width 2ft as:
2ft = 2ft*C = 2ft*12in/1ft = 24in
