42
1) 49, 131
2) 73, 17



​

Answer 1

Answer:

The first pair is supplementary angle .

The second pair is complementary angle.

Step-by-step explanation:

Because , sum of supplementary angle is 180 = 49 + 131 = 180

the sum of complementary angle is 90

90 = 73 + 17 =90

Hope that answer is so useful to you.

Answer 2

Answer:

a pair of completry angles messures 90

so, choose the pair of which the addition is 90 degree

a pair of supplementary angles measures 180 degree

so, cjoose the pair of which the addition is equal to 180 degree.

first pair,

49,131

add both

49+131 = 180

so, this pair is supplementary

second pair,

73,17

add both

73+17 = 90

so, this pair is complementary
