5x2y and 7xy2 are like terms.

True
False

False

The variable portions x^2y and xy^2 are slightly different, so that's why we don't have like terms here.

False

Step-by-step explanation:

Like terms are those terms where they have the same variable

so here

5x2y variables are = 5x and 2y

7xy2 variables are = 7x and y2

you can observe that x variable is same but y variable is not same as 5x3y have 2y whereas 7xy2 have y2#

so the answer is FALSE

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
