Number 5 is a=110  and b= 71. To find a, subtract 65 from 180 because 65 is an alternate interior angle and linear pair. then, to find b, add all of the measurements you have found already and subtract the sum of those from 360.

Number six is the reflexive property because in the reflexive property a=a so it says bd=bd so it follows that property.

How many ways can Mrs. Sullivan choose two
sveta [45]

In 371 ways Mrs. Sullivan choose two  students from 27 to help put away calculators at  the end of class

Step-by-step explanation:

let us assume that Mrs.Sullivan  wants to choose 2 students from a group of 27 students

So ,in the first choice we have  27 students

In the  second choice we have  26 choices

So Mrs.Sullivan has = 27 × 26 = 702 ways

But  each group repeated twice,in order to avoid that we will divide the answer by 2

so we will write

= 702 ÷ 2 =<u> 351 ways</u>

<u>This method of calculation is called Combination</u>
