Find the missing angles

Since we know that angle 2 = 68 degrees and angle 1 is supplementary,

180 = 68 + <1

Subtract 68 from both sides.

112 = <1

4 is opposite of a 90 degree angle, therefore, it is also 90 degrees.

Angle 3 is supplementary to angle 4

180 = 90 + <3

Subtract 90 from both sides.

90 = <3

Since we know two Interior angles, we can find the third.

180 = 90 + 68 + <5

Combine like terms

180 = 158 + <5

Subtract 158 from both sides.

22 = <5

<5 and <6 are supplementary.

180 = 22 + <6

Subtract 22 from both sides.

158 = <6

In conclusion,

<1 = 112

<2 = 68

<3 = 90

<4 = 90

<5 = 22

<6 = 158

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
