Answer:
what? I am so confused. How you worded it is confusing
Step-by-step explanation:
Answer: 135°
Step-by-step explanation:
The sum of the angles in a pentagon is equal to 540°, and the sum of the first four angles is 405°.
70 + 90 + 100 + 145 = 405
540 - 405 = 135
Answer:
No mode
Median: 12
Step-by-step explanation:
there is no mode because there is no 2 or more numbers that are the same
the median is 12 because if you put the number in order: 5,8,9,12,18,22,25 then the middle number is 12

Option ( A ) is the correct answer.
- Sum of all interior angle of a regular pentagon is 540°
- Number of edges in regular pentagon is 5.
- Number of vertices in regular pentagon is 5.
Answer:

Step-by-step explanation:
Quadratic function is function of the form
where a, b and c are real numbers and 
A number is said to be a rational number if it can be written in the form
where u and v are integers and
.
A number is said to be a complex number if it can be written in the form u+iv where u and v are real numbers.
A number 'a' is said to be a zero of a function P(x) if 
We know that if zero of a fraction is of form u+iv then its other zero is u-iv.
As 3+7i is a zero of the function, 3-7i is also its zero.
So, given equation is
