Looks like you did most of it.
The next step would be setting them equal to 105, like the problem suggests.



Then we can plug back in to find the numbers.




The three numbers are
.
Hope this helps.
頑張って!
Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)
To get the interior angles you subtract 180 from 12 to get 168 degrees
In the right triangle, the longest side is the hypotenuse.
Let α be the angle opposite to the side with a length of 12 units, <span>then according to the Law of sines:
</span>

In a triangle, the three interior angles always add to 180° ⇒
third angle = 180 - 90 - 67 = 23°
Answer:
67° and 23° (to the nearest degree).
87% of 73 is about 63.51 and 73% of 87 is 60.59 so 87% of 73 is greater
I really don’t understand this question. can you explain this in the comment so i can answer your
