Answer this question and i will mark you as brainliest trust me i pormise

a. x=65 because of vertical angle theorem,c. 44, b.y= 71 because of  triangle angle sum theorem

Step-by-step explanation:

c. corresponding angle theorem and supplementary angle theorem so z+65+71=180  meaning z= 44

the answer is c. 23/3

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✌✌✌
