______ ft

27 is ∠b larger or smaller than a right angle?

28 a math book contains 130 pages. rounded to the nearest hundreds place, how many pages does the math book contain?

______

Explanation:

Step1: Identify the digit in the ones place for 145

The number is 145, and the digit in the ones place is 5.

Step2: Apply rounding rule for tens place

Since the digit in the ones place (5) is equal to or greater than 5, we round up. So 145 rounded to the nearest tens is 150.

Step3: Analyze angle B in parallelogram

In a parallelogram, adjacent angles are supplementary. If we assume this is a non - rectangle parallelogram, and a right - angle is 90 degrees. Angle B in a non - rectangular parallelogram is larger than 90 degrees.

Step4: Identify the digit in the tens place for 130

The number is 130, and the digit in the tens place is 3.

Step5: Apply rounding rule for hundreds place

Since the digit in the tens place (3) is less than 5, we round down. So 130 rounded to the nearest hundreds is 100.

Answer:

1. 150 ft
2. bigger
3. 100
