SOMEBODY PLEASE HELP!! Find the missing value. Show your work please.
anzhelika [568]
The answer for A would be 8.5 because if you use a^2+b^2=c^2 you would have 12^2 which equals 144 and you would divide that by two to get 72 and then take the square root to find the side length

The answer for be would be 45 because the sum of all angles in a triangle is 180 and you already know one is 90 and 180-90=90 and because this is an isosceles triangle you know the two bottom angles are equal so 90/2=45  <span />

Given the regular polygon below, what is the m41?<br> 1
kicyunya [14]

Answer:

32.72 degrees

Step-by-step explanation:

This is an 11-gon

the sum of INTERIOR angles is (11-2) 180 = 1620

  so each interior angle = 1620 / 11 = 147.2727

     angle 1  is 180 - 147.2727 = 32.72 degrees

Sloan [31]

Answer:

see below    PLEASE GIVE BRAINLIEST!!

Step-by-step explanation:

A)  2.40A ≦ 9.60

B) You can choose to purchase between 0 and 4 avacados.  4 is the maximum you can buy because 2.40 x 4 = 9.60 and that is all the money you have and more than 4 would make the equation incorrect.  0 is the least you can buy since you can't purchase a negative amount of something.

So, A ≦ 4
