Answer:
the given triangles are right triangles which is enough to prove them 'similar'
but not congruent.
Answer:
2,840
Step-by-step explanation:
since the three is in the tens place and 7 in single <em>if 5 and up round up fi 4 and below leave it alone you</em> will then take the 3 and round up to give you 2,840
Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.
Hope this helps :)
