Answer:
The answer is y=20
Step-by-step explanation:
If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.
Next, add angles B and C together to get 50.
Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.
Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)
Next, slove the equation.
- 3y+120 = 180
- -120 -120
- 3y = 60
- /3 /3
- y = 20
And theres your answer, I hope I helped. Put any questions in the comments.
