Brainliest I will give pls help me

Step-by-step explanation:

a) complimentary angles = 90°

so,

let the complement be x,

so after inserting values we got,

72.5° + x = 90°

→ x = 90.0 - 72.5

→ x = 17.5° ans

supplementary angles = 180°

let the supplement of 72.5° be x

so, after inserting values we got,

72.5 + x = 180°

→ x = 180.0 - 72.5

→ x = 107.5° ans

and I have no idea about b...but hope this answer helps you dear!
