1. In the diagram, AB is parallel to CD. X
A
— В
72°
C С
D
(a) Work out the size of the angle marked X.
(b) Give a reason for your answer.

x= 72°

reason: this is because it is a corresponding angle. Corresponding angles are equal to another

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
