Answer:
x = 63
Step-by-step explanation:
This is a right angle, and we know that there are 90 total degrees in a right angle. Because of this information, we know that the degrees of both angles, added together, should come out to 90. This reasoning looks like this:
Now, it's much easier to solve for x. I'll start by removing the parentheses and combining like terms.
Now, let's remove 27 both sides to isolate x and figure out what it's equal to.
So, the measure of x is 63 degrees. We can make sure this is correct by using our equation:
Is 
? Yes, because 63 + 2 is equal to 65, and 65 plus 25 is equal to 90. So our answer is correct.

Answer:
54
Step-by-step explanation:
Answer:
84 in . . . or . . . 7 ft
Step-by-step explanation:
The given scale is the ratio of drawing size to real size.
1/12 = (7 in)/(actual height)
Multiplying this equation by 12(actual height) gives ...
actual height = 12·7 in
actual height = 84 in = 7 ft
average, petite, and tall
50 people are surveyed about favorite preference
450 pairs ordered
average = 25/50, which is half
25/50 = ?/450
so ?/450 = 1/2
450 / 2 = 225, so 225 pairs should be average length.
