Ill give brainliest for name 3 pairs of complemantary angles. if number 8 is wrong tell me but also pl with number

Complementary angle add up to 90 degrees

UOI and UIO  Triangles add to 180 and the IUO is 90 degrees so that leaves 90 degrees to the other 2 angles

AOU AND UOA Triangles add to 180 and the AUO is 90 degrees so that leaves 90 degrees to the other 2 angles

AIE AND EIA Triangles add to 180 and the IEA is 90 degrees so that leaves 90 degrees to the other 2 angles

supplementary angle add up to 180 degrees

Complementary pairs: UOI and UIO , AOU AND UOA ,AIE AND EIA

AUO and IUO  Straight lines add to 180

AEI AND OIE  2 corners of the figure

EAO  AND AOI 4 sided figures add to 360 and the other 2 corners are 90 each which is 180 so that leaves 180 for these 2 angles

Supplementary pairs: AUO and IUO ,AEI AND OIE, EAO  AND AOI

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
