Can I have the answers for both questions pls! : ) it's due in tomorrow morning

B) y = 35°                

Step-by-step explanation:

Any quadriteral is you can add a line that links opposite corners of the quadrilateral and split it into two triangles. Added a single line the links opposite vertices of the quadrilateral and that splits it into two triangles. The angle rule that angles in a triangle add up to 180 degrees so the angle must add up to 180 degrees because of that angle rule and then in the other triangle the angles in that one must add up to 180 degrees. But the quadrilateral is made up of both triangles so you need all the angle in both those triangles to make up the angles of the quadrilateral so two lots of 180 degrees make up for 360 degrees. (180° plus 180° = 360°)

B) 118° plus 67° pus y plus 4y = 360°          ( add all the angles that are inside of the quadrlateral)

185° plus 5y = 360°                   ( 118 degrees plus 67 degrees is 185°, 5y from to y plus 4y. its like you have 1y plus 4y)

5y = 360° - 185°           ( subtract 180 degrees from both sides)

5y = 175°

divide by both side by 5, the value of y is 35°
