y? i thought it was true the sum of the non-adjacent angle equal y

Answer 6

@nesha

Answer 7

joanna is this true?

Answer 8

well, there's an easy way to know for sure

let's label the third angle as z, as shown:

Answer 9

y + z = 180, since these are supplementary anles
2x + z = 180, since these are the sum of the angles in a triangle

from these two equations we can see that y = 2x, so yes, your statement is true

Answer 10

as a general rule, then yes, the sum of two non-adjacent angles will be equal to the outside angle

Answer 11

awesome so this applies for all triangles like this right?

Answer 12

ok thank u vocaloid i wasnt sure

Answer 13

yes, this will apply for all triangles like this

Answer 14

thank you
