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. )
(-3,5)(-3,3)
slope = (y2 - y1) / (x2 - x1)
slope = (3 - 5) / (-3 - (-3) = -2/0....this means the slope is undefined...u have a vertical line and ur equation of the line would be x = -3
