Always get confused with these questions.

The answer to your question is z = 68

Step-by-step explanation:

The sum of the internal angles in a polygon equals 180(n - 2)

In this polygon n = 5

                         180(5 - 2)

                          180 (3) = 540

Then

              119° + 2z + 11 + 70° + 2z + z = 540

Simplify like terms

               5z = 540 - 119 -11 - 70

               5z = 340

               z = 340 / 5

              z = 68        

your answer is b.

step-by-step explanation:

the 2 points are: (3,1) and (6,6)

first, let's find the slope:

(6-1)/(6-3) = 5/3

then let's plug this into the point-slope formula:

y - 1 = 5/3(x - 3)

this is your answer! the below is just the simplified form.

y - 1 = 5/3x - 5

y = 5/3x - 4
