Answer:
Part A: 13.2
Part B: see below
Step-by-step explanation:
<u>Part A</u>:
13.245 rounded to tenths is 13.2
<u>Part B</u>:
The rule is ...
<em>Add 1 in the number place you're rounding to if the digit to its right is 5 or more. Drop (or zero) all digits to the right of the place you're rounding to.</em>
Here, the digit to the right of the tenths place is 4, so no action is taken other than dropping digits to the right of the tenths place.
Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
<u>1) Identify angle relationships</u>
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
<u>2) Solve for angle 6</u>
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
