In a survey 200 people were polled at a local shopping center about spending free time playing sports, watching a movie, or reading a book. the relative frequency table below displays the results. movies sports read male 0.25 0.30 0.10 female 0.15 0.05 0.15 a. how many males surveyed preferred playing sports? b. how many people surveyed preferred to read a book? c. how many females were surveyed?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
