Maria is to select one number from the set {60,61,62,63,64,65,66,67,68,69} at random. consider the following three events. event x: the selected number is an even number. event y: the selected number is a multiple of 3. event z: the selected number is a multiple of 5. part a: list the outcomes that are in event x or in event y but not in both events. part b: list the outcomes that are in both events x and y but not in z.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: 7

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

$113.42

i hope that is right.
