Opposite sides of angles are equal so
x+12=4x-48
12+48=4x-x
60=3x
x=60/3
x=20
Answer:

Step-by-step explanation:
I'm sorry if this doesn't help u but I'm doing homework too so I need to hurry up and finish it ._.
Consider this decimal as a fraction.
We have:

We now can take the square root of the numerator and the denominator separately for a result of 16/10, or 1.6.
Answer:
A. 30.144
Step-by-step explanation:
This is a Chi-Squared test
Given:




- The significance level is 5%, so

To use the Chi-Square distribution table, you need to know two values:
- Degrees of freedom = (n - 1)
- Significance level
Degrees of Freedom = n - 1 = 20 - 1 = 19
The significance level is 5%, so 
This is a one-tailed test since
so Upper tail area = 0.05
Reading from the table (attached), the critical value is: 30.144
(This means that we reject
if the test statistic is greater than 30.144)
