I believe this one is C but none of the equations seemed to work for me when I imputes them into a graphing calculator. Not sure what I did wrong or if maybe the question is wrong. Hope this helps!
Answer:
side c = 10.2
A = 52.6°
B = 37.4°
Step-by-step explanation:
c² = 8.1² + 6.2²
c² = 104.05
c = 10.20049018
Using cosine law:
8.1² = 10.2² + 6.2² - 2(10.2)(6.2)cos
cosA = 7687/11648
A = 52.57199409
A = 52.6°
B = 180 - 90 - 52.6 = 37.4°
You can just overall divide 100 from 25 to get a percentage because you're trying to find the percentage of captown only but per se if you were to find various cities in Maltania than you can just divide 100 by the percent of the population.
All you need to know is that if the lines are the same and is not touching or intersecting then they are parallel. Parallel lines never intersect, those will be perpendicular lines.
