Can someone explain how to find x and y i don’t understand this at all

To find y you must recognize that 141+3y=180 . You know this since half of a circle is 180, and a line is basically half a circle if you arc from end point to end point.

You can then subtract 141 from both sides,

3y = 39

Then divide both sides by 3,

y=13

You would want to use 39° for 3y° since 3·13= 39.

A triangle can only contain 180°, so you would add 68 and 39 together and then subtract this from 180 to give you x.

68 + 39 + x = 180

107 + x = 180

x = 73

4444444444444 i think

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
