A survey was given to adult residents in a particular city. It found that 29% of the residents regularly use public transportation, and 78% of the residents have the ability to drive. 12% of the residents regularly use public transportation AND have the ability to drive. Find the probability that an adult resident in this city regularly uses public transportation, given that he or she has the ability to drive. Round your answer to the nearest hundredth.

step-by-step explanation:

it would open into a square depending on the type of envelope i’m not sure about the second part

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.
