∠x and ∠ y are supplementary angles. ∠y measures 57°.what is the measure of ∠x?

options:

123
45
140
33

supplementary angles add to equal 180. so x + 57 = 180. solve for x and you get 123.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
