Ответ:
Notice that C has a clockwise orientation. By Green's theorem, we have
where D is the triangule region with C as its boundary, given by the set
So we have
Ответ:
x=60
Step-by-step explanation:
So basically the sum of interior angle of a triangle is 180.
Add all the values and make it equal to 180.
x+3/2x+1/2x=180
Then find x
3x=180
x=180/3
x=60 degrees
