:( this is due by the end of the day! 20 points!! right answer please

∠c=90°, ∠b=47.5°, a=85°

Step-by-step explanation:

∠c is inscribing a semicercle so is half of the intercepted arc and the whole circle is 360 , half will be 180 and the angle will be 90°

∠b is inscribing a 95°arc so is half of that 95/2=47.5°

arc a is part of a semicircle so is 180-95 =85°

idk

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✌✌✌
