Answer:
Step-by-step explanation:
Find a common denominator or greatest common factor. 63 and 27 are both multiples of 9. When you divide each by 9 you get 7:3. 14 and 6 are both multiples of 2. When you divide each by 2 you get 7:3 again. So these ratios are equivalent.
Start with any set of numbers. Multiply them each by the same factor and the new set will be an equivalent ratio.
Answer:
A. Building A, it is around 100.69 feet taller than building B.
Step-by-step explanation:
Since building A is 120 feet away at and elevation of 
, then:
Tan = 
Where x is the height of the building at the horizontal plane.
x = Tan × 120
= 100.692 feet
For building B at the same elevation,
Tan = 
x = Tan × 60
= 50.346 feet
Since the angle of elevation are the same, building A is around 100.69 feet taller than building B.
Some key definitions:
<u>Reflexive property:</u> angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.
<u>Symmetric property:</u> you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.
<u>Transitive property:</u> If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.
So for the first clue, you have the reflexive property.
The second clue is the symmetric property.
The third clue is the transitive property.
Answer:
