Answer:
y=95
Explanation:
we know that the triangle angles sum is 180°
to find Y you should find x
we are going to find x, we know that a straight angle is 180, to find the x you should:
move 120 to the other side with a negative sign:
angle
now we know enough angles to find y:
25 is given in the picure and 60 is the x angle while 180 is the sum of a triangle angles, we have to flip the equaton to find y:
