Let be the measure of the angle labeled in the attached image below. By the law of sines,
and
Then
From here we can solve for :
.
Answer:
here 1st case
x+y=77
or,x=77-y
second case
4x+2y=286 (according to question)
putting value of x from first case
4 (77-y)+2y=286
or,308-4y+2y=286
or,308-286=2y
or,22=2y
or,11=y and x=77-11
x=66
Step-by-step explanation:
so,y=11 and x=66
