Answer:
60
Step-by-step explanation:
60 as it equaliteral all side are 60
➷ As it is an equilateral triangle (meaning all the lengths are the same), all the angles would be the same.
Therefore, y is 60.
Alternatively, you know that angles in a triangle equal 180 degrees so you can do this:
180 - (60 + 60) = 60
In short, your answer is option A, 60 degrees

y= -5-x
-x + 5(-5-x) = -7
-x -25-5x =-7
-x-5x = 25 -7
-6x= 18
x = -3
-3 +y = -5
y= -5 +3
=-2
-(-3) + 5(-2)
3 - 10 = -7
you can use the pythagorean theorem. form a triangle, the distance on one side should be 6, the other 1.
