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!

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

that is the sum
