Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
If sides are congruent then the angles ACROSS from them are also congruent.
Since WV and VU are congruent, angle U is congruent to angle W.
Set up an equation and solve.
See attachment.
x = 8
Angle w = 63
Answer:
2.- 100
Step-by-step explanation 1:
↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.
Step-by-step explanation 2:
↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.

Answer:
the numerator is 12
Step-by-step explanation:
since 48 is a percent, it would be put as 48/100 as a fraction. since both the numerator and denominator are divisible by 4, you can reduce the fraction into 12/25. Since the question is asking what the numerator was when the denominator was 25, the answer is 12.
