Consider triangle abc what is the value of y in the triangle
Yakvenalex [24]

Answer:

y = 50

Step-by-step explanation:

All triangle angles add up to 180 degrees.

To set this equation up, you need to add everything given in the triangle and set it equal to 180:

y + y + 80 = 180

<em><u>Add like terms:</u></em>

2y + 80 = 180

<u><em>Subtract 80 from both sides:</em></u>

2y + 80 = 180

     - 80   - 80

___________

2y = 100

<u><em>Divide both sides by 2:</em></u>

y = 50

<u><em>If you're unsure, you can plug in the 50 for y:</em></u>

y + y + 80 = 180

50 + 50 + 80 = 180

100 + 80 = 180

180 = 180

Water is something that leads things to rust. Exposure to air also leads things to rust. Exposure to both of them will completely rust the nail if given time.
