Answer:
1. Line c
2. She subtract when she suppose to add
3. 2x-12+12 = 10+12
2x = 22
x = 22/2 = 11
x is 11
Answer:
Length of the escalator is 33.94 feet.
Step-by-step explanation:
In the attached figure we can see that

It is given that
angle = 45
Vertical Height 'V' = 24 feet
Applying values in the above equation we get

The answer is C, 10 7/15 !
Answer:
x=16
Step-by-step explanation:
Complementary angles add to 90 degrees
T + V = 90
2x+10 + 48 = 90
Combine like terms
2x +58 = 90
Subtract 58 from each side
2x+58-58 = 90-58
2x = 32
Divide each side by 2
2x/2 = 32/2
x = 16
Can't be. It's a decimal.
