An exterior angle is formed by one side of the triangle, and a side EXTENDED outside the triangle. Two angles are like that, ∠4 and ∠2.
Angle 3 is NOT an exterior angle because it is made up of two extended sides. It does not use one of the sides of the triangle.
Answer:
x ≤ 18
Step-by-step explanation:
The ≤ symbol means "greater than or equal to". Since it is 'no more' than 18, that means it can be 18 or less. Thus, less than OR equal to. Hope I helped.
46.19 should be the answer
I don't believe so, last time i checked for two lines to be perpendicular they needed to have opposite reciprocal slopes.
For Example
If one line has a slope of 5
The second line has to have a slope of -1/5
