Answer:

Step-by-step explanation:
Step-by-step explanation:
11. shape 1 => A = ½×17×10=85m²
shape 2=> A = 17×9 =153 m²
total area = 238 m²
12. shape 1 => A = 7×3= 21 m²
shape 2=> A = 3×2 = 6 m²
total area = 27 m²
subtract 6 from the 21x+6. Then divide by 21. The answer is going to be -6/21
Answer:
Part 9)
Part 10)
Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side
Part 9) we know that
Point Q is the midpoint segment XY (QY=QX)
Point R is the midpoint segment XW (RW=RX)
Applying the Midpoint Theorem
RQ is parallel to WY
and
we have
substitute
solve for x

Part 10) we know that
Point B is the midpoint segment TS (BS=BT)
Point C is the midpoint segment RS (CS=CR)
Applying the Midpoint Theorem
BC is parallel to TR
and
we have
substitute
solve for x
