Step-by-step explanation:

180 - 100=80

x=80 because it is vertical from from 80.

6y = 90

90+90+ 180. it would be 90 because each side is a right triangle.

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✌✌✌
