Answer 1

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
