Given: In circle O, m BAC = 290. So angle COB = 70 and angle CAB = 35
So angle COB = 70 and angle CAB = 140
So angle AOB = 70 and angle CAB = 120
O O
O So angle AOB = 120 and angle COB = 60

step-by-step explanation:

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✌✌✌
