Answer:
5n8n+5-5n in its simplest from is 5n^9n+5-5n
Step-by-step explanation:

Whenever two lines intersect, they form two pairs of vertical angles. Vertical angels have a common vertex, but they are never adjacent angles. Fin, vertical angles are always congruent.
Explanation:
1.angels on a straight line add up to 180degrees
2.when you see the signs at number 6 and 7 it means it is 90 degrees
EG. number 6.it will be 90degrees+29degrees=119degrees remember that all angles on a straight line add up to 180 degrees. to get angel xwy you will subtract 119 degrees from 180 degrees =xwy which is 61 degrees
Answer:
Step-by-step explanation:
- If AB=BC=CA, it means ABC is an equilateral triangle which all three sides are equal.
- Thus, all three internal angles are also congruent to each other and are each 60°.
