The line is right in the middle of 100 and 110 degrees so the answer should be 105 degrees. This tool is called a protractor. :)
Answer: that would be 76% hope that helps
Step-by-step explanation:
By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
⅓x² +11x-75<105
⅓x² +11x-75-105<0
⅓x² +11x -180<0
x² +33x - 540<0
(x+45)(x-12)<0
(x-12)<0 or (x+45)>0
x<12 or x >-45
answer is A
