The answer is 27, but I might be wrong
Answer: option c.
Step-by-step explanation:
You need to remember the identity:

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "R":
You know that you need to find the measure of "R" and
(which is the opposite side) and
(which is the adjacent side), you can sustitute values into 
Then, you get:

Answer: Always.
Step-by-step explanation:
The transitive property holds true for similar figures always because similar figures have similar shapes, the same angles and dimensions are proportional.
For example:- If figure 1 is similar to figure 2 then both have same shape and same angles and dimensions are proportional .
If figure 2 is similar to figure 3 then both have same shape and same angles and dimensions are proportional .
⇒ figure 1 is similar to figure 3 the both have same shape and same angles and dimensions are proportional as the figure 2 .
Thus the transitive property holds true for similar figures always.
The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches
The dimension of the mirror is given as:


From the center of the mirror to the floor of the wall, the distance is:

So, the distance to the top of the mirror will be:

Substitute 24 for height


Convert feet to inches



The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.
So, we have:

Convert feet to inches



Hence, the distance is 21 inches
