Answer:
a. see below for diagram. Angle for the length; length for the angle
b. 6.84°; not to code
c. 36.1 ft
Step-by-step explanation:
a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.
__
b. The angle the ramp makes can be found using the tangent relation.
Tan = Opposite/Adjacent
tan(angle) = 3/25
angle = arctan(3/25) ≈ 6.84°
The ramp will make a 6.84° angle with the ground. It will not meet code.
__
c. We can find the distance from the building where the ramp must start using the same trig relation.
tan(4.75°) = (3 ft)/(distance)
distance = (3 ft)/tan(4.75°) ≈ 36.1 ft
The ramp must start 36.1 feet from the building to exactly meet code.

x can pretty much be any number possible. It will just equal something different every time.
Answer:
Step-by-step explanation:
<u>Given:</u>
- Greatest common factor = ?
GCF is the highest number (or expression) that divides exactly into two or more numbers (or expressions)
<u>Let's find the factors first:</u>
We can see the second expression 18xy is the factor of the first expression
Therefore, the 18xy is dividing foth of the expressions, so it is the GCF
