Help me please thank you

a) 98 degrees.

b) 8 degrees.

Step-by-step explanation:

supplementary angles: 2 angles that add up to 180 degrees.

a) to find the supplementary angle, all we have to do is:

180 - 82 = 98 degrees

Complementary angles: 2 angles that add up to 90 degrees.

b) to find the complementary angle, all we have to do is:

90 - 82 = 8 degrees

Hope that helped : )
