Step-by-step explanation:
2/6 is litterally right there cause it has seven lines and tge 0 doesnt count
<u>Let's take this problem step-by-step</u>:
<u>The ;unlabeled angle' adjacent to the 'outside angle of measure 78°'</u>
⇒ is on a straight line
⇒ sum of angle measure = 180 degrees

<u>Now we know:</u>
⇒ sum of all angles in a triangle ⇒ 180°
<u>Let's put that in equation form and solve:</u>

<u>Answer: 21°</u>

We can’t measure these. How long is each of them
<h3>The formula to find unit rate is:</h3>
<em>divide the denominator with the numerator in a way that the denominator becomes 1</em>

<u>Hence, The unit rate is 16 rooms per floor.</u>
2.86-2.81=0.05
(0.05/3.86)x100=1.75%
