<u>Equation of a line</u>
To define the equation of a line, we only need two points through which it passes. The graph shows two clear points to choose: (0,2) and (1,-1)
Set up the equation of the line by using the formula
Operating
Rearranging
The missing reason in step 3: is vertical angles are congruent, while the missing reason in step 5 is: definition of congruency.
<h3>What are Vertical Angles?</h3>
Two angles are referred to as vertical angles is:
- They share the same vertex angle.
- They are non-adjacent angles.
- They do not share a common side.
<h3>What is the Vertical Angles Theorem?</h3>
According to the vertical angles theorem, two angles that are vertical angles must be congruent to each other, that is, they are equal in measure.
In the image given, as attached below, angle EDF and angle ADC are vertical angles pair. Therefore, based on the vertical angles theorem, they have equal measure (they are congruent to each other).
Thus, the missing reason in step 3: is vertical angles are congruent, while the missing reason in step 5 is: definition of congruency.

I want u to do 5.50 ×75 ÷ 100 and you will find your answer
Answer: 60 degrees
Step-by-step explanation:
Since we know that the sum of the angles in a triangle is 180 degrees, that means x + x+ x = 180.
3x = 180
x = 60.
Another way we could figure out that x = 60 was by realizing that this is an equilateral triangle, which means each angle must = 60 degrees.
