Answer:
<em>45 and 135</em>
Step-by-step explanation:
The sum of any interior angles will be 180 so you divide 180 by 4. And you get <em>45</em> then you multiply that by 3 and you get <em>135</em>
The total mass was 149.5 grams.
Setting up an equation, we have that the sample size, 39.1, is 5 3/4 (5.75) grams less than 3/10 of the total mass; this gives us
39.1 = 3/10x - 5.75
Adding 5.75 to both sides, we have
44.85 = 3/10x
Multiplying both sides by 10,
448.5 = 3x
Dividing both sides by 3,
149.5 = x
n+9=n-6 is the equation for this problem
