Question

Once 4 students from class IX F were selected for plantation of flower plants in the school garden. The selected students were Pankaj. Raju. Deepak and Renu . As shown PQ and MN are the parallel lines of the plants. Pankaj planted a sunflower plant at P. then Raju planted another sunflower at Q. Further, Deepak was called to plant any flowering plant at point M. He planted a marigold there.Now it was the turn of Renu, She was told to plant a flowering plant different from the
three planted one So she planted a rose plat at N.There was a water pipeline XY which intersects PQ and MN at A and B and XBN = 60°

C 180

d. 100

iv. Which angle is the corresponding angle to a?

a. Zz

b. p

c. Zb d. Zq

v. What is the value of (p+q+a+z)/6?

a. 60

b. 120"

C. 180°

d. 100"

​

Answer 1

Answer:

i) According to the diagram,

60+z=180

z = 180 - 60

z = 120

ii)According to the diagram,

x = 60 ( corresponding  angles )

iii) we know that linear angle = 180 degree

 p + q = 180

iv) The corresponding angle to a is angle q

v) According to the diagram p+q = 180

( linear pair )

a+z =180  (linear pair )

thus, 180 + 180 = 360

according to the question,

360 degree / 6 = 60 degree
