Answer:
question 3 answer : 40 , 60 , 100 , 160
question 4 answer : x = 34 ; y = 35
Step-by-step explanation:
Question 3 ) let the angles of quadrilateral are 2x , 3x , 5x , 8x,
the sum off all angles of quadrilateral is 360
∴ 2x + 3x + 5x + 8x = 360
= 18x = 360
= x = 20
hence the angles are
2x = 2 * 20 = 40 ; 3x = 3 * 20 = 60 ; 5x = 5*20 = 100 ; 8x = 8 * 20 = 160
Question 4 ) sum of two adjacent angles in parallel lines are 180
so ,
2y - 5 + 3y = 180
= y = 35
opposite angle in pparrallellogram is equals
so ,
3x + 3 = 3y
3x + 3 = 3 * 35
x = 34
