So from A to B. We can see that the coordinate point a is at negative 3 and at the point B is at negative 1. We can find the length of this line segment by taking a minus B on the number line or B.
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. )
