Answer:
<h3>1. x = 15° | y = 120°</h3><h3>2. x = 4.5 | y = 60°</h3>
Step-by-step explanation:
1. 4x° + 4x° + 4x° = 180° ( The sum of all interior angles of any triangle is equal to 180° )
4x° + 4x° = y° ( An exterior angle of a triangle is equal to the sum of its two interior opposite angles. )
2. y° + 60° + 60° = 180° ( The sum of all interior angles of any triangle is equal to 180° )
All three internal angles are also congruent to each other and are each 60°. Therefore this is a equilateral triangle.
Perimeter = 4x + 4x + 4x ( An equilateral triangle is a triangle with all three sides of equal length. )

______
1234 aka. 1,200 + 20 + 14
X+2y=5
x = -2y+5
-2(-2y+5) - y = -4
4y - 10 -y = -4
3y - 10 = -4
3y = 6
y = 2
x + 2(2) = 5
x + 4 = 5
x= 1
Therefore, the coordinates are (1,2).
