Step 2 correct
Step 3 correct
Step 4 incorrect: It must be
y² - 10y + 25 = 2x + 23
Step 5 incorrect because step 4 incorrect
Step 5 must be : 1/2(y - 5)² - 23/2 = x
Answer:
120, 114, 126
Step-by-step explanation:
Since these are all exterior angles, they will all always add up to 360°. Since we know this, you can set up an equation and it would be x+(x+6)+114=360. When added you get 2x+120=360. Now subtract 120 on each side to get 2x equals 240. Then you divide by 2 and get that x is 120. Now all you have to do is plug x into the equations for the angles so they would be 120, 114, and 120+6 so 126. Now you have 120,114,and 126 as your angles. To check, just add all the angle measurements up and it should equal 360.
The correct one is option 1.sphere
