8 0

Answer:

x =89

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360 degrees

88+154+x+29 = 360

Combine like terms

271 +x = 360

271+x-271 = 360-271

x =89

CaHeK987 [17]

Answer:

The answer would be B: 8 ones, 4 tenths, and 5 hundredths.

Do the math, and 1.57 + 6.88 = 8.45

Now look at the answer choices. You can automatically get rid of every answer choice but B because none of them have an 8 in the ones place.
