Answer:
4 m
Step-by-step explanation:
The geometry is that of a right triangle with hypotenuse 8.5 m and one side of length 7.5 m. If "b" represents the distance from the base of the ladder to the wall, the Pythagorean theorem tells us ...
b² + 7.5² = 8.5²
b² + 56.25 = 72.25
b² = 16 . . . . . . . . . . . . . subtract 56.25
b = 4 . . . . meters . . . (take the square root)
The base of the ladder is 4 m from the wall.

You may recognize this as the 8-15-17 Pythagorean triple, scaled by 1/2.
Answer:
< A=72°
<C=72°
Step-by-step explanation:
Solve 5y-3=3y+27
Since 0.8 is the tenths place, and it is rounded from .799, it is to the tenths place. If the answer was written as .80, it would be to the hundredths place, as that would specify more accuracy in this answer.
More likely to flip heads on the first.
