Answer:
The measure of x is 
Step-by-step explanation:
we know that
The formula to calculate the sum of the internal angles of a polygon is equal to

where
n is the number of sides
In this problem we have

substitute

Find the measure of each internal angle
Divide the sum of the internal angles by the number of sides

The value of x is half the measure of internal angle
so

Answer:
<h2><u>440 ft.²</u></h2>
Step-by-step explanation:
Surface area of the object = 2 (lw + wh + hl) = 2 (10× 6 + 6 × 10 + 10 × 10)
= 2 ( 60 + 60 + 100) = 2 × 220 = 440 ft.²
Answer:
1 5/6 miles
Step-by-step explanation:
first, we take the amout ethan lives from school, and turn it into a mixed number

so, we have to subtract that from how far away ethan lives
29/12 - 7/12 = 22/12
22/12 simplified is 1 10/12 or 1 5/6
