Since each side is r times the side of ABC, then 30*r+40*r+60*r is the perimeter, which equals 130r (by separating it into r*(30+40+60) using the distributive property)
Answer:
Step-by-step explanation:
When two straight lines intersect, 2 pairs of vertical angles formed are congruent.
Therefore,
Use this equation to solve for x as follows:
Subtract 5 from both sides
Subtract 2x from both sides
Since there are 55 choices, we have to have 55 options, and for 44 questions, we multiply how many options there are in 1 question by 44 to get 55*44=2420
