So, we know that the internal angles of a triangle add up to 180 degrees, yes?
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.
Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too!
Hope I helped!! :)
Hey there!
GUIDE:
2 negatives = positive
2 positives = positive
1 negative & 1 positive = negative
1 positive & 1 negative = negative
ANSWERING THE GIVEN QUESTION
y = -4x
y = -4(7)
y = -28
Because, remember we said a NEGATIVE (-4) & a POSITIVE (7) gives you a negative [-28]
Therefore, the answer should be: -28
Good luck on your assignment & enjoy your day!

Answer:
3
Step-by-step explanation:
The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle
solve
115+z=180
subtract 115 from boths ides
z=65
answer is third angle=65 degrees
