Answer:
10. 105
11. 75
12. 75
13. 105
14. 75
15. 105
Step-by-step explanation:
Notice that 75? Anything that is adjacent (has a common vertex like 75º) to the vertex is a linear pair. here is an example below:
Since there is only THAT 75, you must find the supplementary angle (adds up to 180). and remember in order to get a supplementary angle it has to be a STRAIGHT LINE and HAS TO EQUAL 180. (4, 1 in your image)
180 - 75 = 105.
and also it's also a linear pair so it reflects too which makes things a lot easier!
So, if 4 is 75 and it reflects, then that means 2 is also 75. 1 is 105 and it reflects so 3 has to be 105. and the same for the rest of the numbers.
Hope this makes sense

Answer:
<u>The correct answer is A. 1 +/- i √31/2</u>
Step-by-step explanation:
Let's use the quadratic formula to solve the equation:
x² - x + 8 = 0
Let's recall that the quadratic equation is:
x = (-b +/- √(b² - 4ac))/2a
In the equation, a = 1, b = -1, c = 8.
Replacing with the real values, we have:
x = (-b +/- √(b² - 4ac))/2a
x = (- (-1) +/- √(-1² - 4 (-1) (8)))/2(1)
x = (1 +/- √( 1 - 32)/2
x = (1 +/- √( - 31)/2
x = (1 +/- √( -1 * 31)/2
Let's recall that √ -1 = i
x = 1 +/- i √ 31/2
<u>The correct answer is A. 1 +/- i √31/2</u>
