Answer:
D. 13.8
Step-by-step explanation:
FE being the midsegment means E is the midpoint of BC. The midpoint divides the segment into two equal parts, so BE = EC = 6.9. The length BC is the sum of those parts:
BC = BE +EC = 6.9 +6.9 = 13.8
The length of BC is 13.8 units.
<span>Use a proportion:
x/(5 1/2) = 50/4
--------
x = (11/2)(50/4)
--------
x = 550/8
----
x = $68.75</span>
<u>Answer:</u>
<h2>
18.38</h2>
<u>Explanation:</u>
since this triangle is a right-angled triangle and one its angles equals 45° then it's an <u>isosceles right triangle</u> which means that the side opposite 45° <em>(the side to the left)</em> is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
<em>note:</em><em> in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!</em>
Answer:
Since M is the Midpoint.
M(-7,1)
A(-4,-4) N(x,y)
From Midpoint Formula
-7 = -4 + x/(2)
-14=-4+x
x=-10
1=-4+y/2
2=-4+y
y=6.
N has the points (-10,6).
