<u>Answer:</u>
- The value of x is 120.
<u>Step-by-step explanation:</u>
<em>Draw an extra line. You can do it in any direction. You can see that the extra line you drawn, forms an angle. The angle must be equal to 50 or 70 because of alternative inner angles. With the help of the triangle properties, you can find the value of x.</em>
<u>We know that:</u>
- 70 + 50 + (180 - x) = 180
<u>Work:</u>
- 70 + 50 + (180 - x) = 180
- => 120 + (180 - x) = 180
- => 120 + 180 - x = 180
- => 300 - x = 180
- =>
Hence, <u>the value of x is 120.</u>

Answer:
1) (x-6)^2=49
2) C
Step-by-step explanation:
Subtract 12 x and you get
-x^2-12x+13=0
You will be left with, after making a perfect square
(x-6)^2=49
To get rid of the squared/2nd power, add plus or minus to the opposite side and square root both sides. You will be left with
x-6=plus or minus 7
Your answer comes out to the to problem. Setting both to 0, you get -13, and 1. -6 plus 7 is 1, and -6 plus a -7 is -13.
