Can any math genius help me with this

Here's my working for 1) You need to find the exterior angle, then divide by 360 to find the number of sides:

Applying these steps :

180 (Interior Angles) - 162 = 18 (Exterior angle)

360 ÷ 18 is 20 sides

For 2)

Its the same method, so apply the steps:

180 - 175 = 5

360 ÷ 5 = 72 sides

Hope it helps! :)

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
