Answer:
y=30, x=8
Explanation:
right angle =90
the angle of a triangle =90-40=50 degrees
the image shows two parallel line with perpendicular line that holding angle 40 and 3y
3y=90 degrees
y=90/3=30 degrees
the sum of the angles of triangle =180
3y+5x+50=180
3(30)+5x+50=180
5x=180-90-50
5x=40
x=40/5=8
the angles are 50,90,40
