Formula
---------------------------------------------
Sum of all exterior numbers = 360°
---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360
---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360
---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108
---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54
---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°
---------------------------------------------
Answer: 99°

Answer:
B is the awnser
Step-by-step explanation:
I just took the etest!!!
6/11y=-18/22
Least Common Denominator is 11: 6/11y=-9/11
Multiply both sides by 11: 6y=-9
Divide both sides by 6: y=-9/6
Simplify: y= -3/2 OR -1.5
Answer:-10/13
Step-by-step explanation:
3x+4 = (2/5)x + 2
First move the 4 to the other side by subtracting it.
it becomes : 3x = (2/5)x - 2
then multiply everything by 5 to get rid of the fraction.
it becomes 15x = 2x -10
then move the 2x to the other side by subtracting it.
you get 13x = -10
now you can divide everything by 13 to isolate the x.
and you get x = -10/13
