Answer:
Part A) Option A. QR= 3 cm
Part B) Option B. SV=6.5 cm
Step-by-step explanation:
step 1
<u>Find the length of segment QR</u>
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
so
In this problem Triangle QRW and Triangle QSV are similar by AA Similarity Theorem
so
we have
---> because S is the midpoint QT (QS=TS)
--->because V is the midpoint QU (QW+WV=VU)
--->because V is the midpoint QU (QV=VU)
substitute the given values
solve for QR
step 2
Find the length side SV
we know that
The <u><em>Mid-segment Theorem</em></u> states that the mid-segment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this mid-segment is half the length of the third side
so
In this problem
S is the mid-point side QT and V is the mid-point side QU
therefore
SV is parallel to TU
and
so
Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Then, plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done much swiftly that way. It does not matter which ordered pair you choose::
−5 = 4 + b
If you want it in <em>Standard Form:</em>
y = 4x - 9
- 4x - 4x
_________
_______________________________________________
3 = 4[3] + b
12
y = 4x - 9
- 4x - 4x
_________
** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.
