First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48
Answer:
3 pi
Step-by-step explanation:
We already know that the sum of the angles adds up to 360.
Therefore we get 73+ 104+ 43 + x = 360, where x = 140
arc length =
were the angle is 140 and r = 4. The radius was given.
Hope this helps.
