28. Which expression has a value that is greater than 42.537?
Explain as well please

A

Step-by-step explanation:

40×10=40

2×1=2

5×1/10=0.5

2×1/100=0.09

3×1/1000=0.003

40+2+0.5+0.09+0.003=42.593

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
