If two angles are supplementary and one of them is 30 , what is the measurement of the second angle?
a. 180
b. 90
c. 60
d. 150

Hello there!

If you have a line (with a plane angle of 180°) and a segment that cuts the line, the two angles generated by the line and the segment are supplementary, and the sum of them should be equal to 180°

if one of the angles is 30°, then the other angle should be:

180° - 30° = 150°

then the right answer is option D.

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
