_____ are ______ midsegments of ΔWXY.

iVinArrow [24]

Answer:

The perimeter of Δ WXY is 14.50 cm ⇒ the last answer

Step-by-step explanation:

* Lets explain how to solve the problem

- There is a fact in any triangle; the segment joining the midpoints of

two side of a triangle is parallel to the 3rd side and half its length

* Lets use this fact to solve the problem

- In Δ WXY

∵ Q is the midpoint of WX

∵ R is the midpoint of XY

∵ S is the midpoint of YW

- By using the fact above

∴ QR = 1/2 WY

∴ RS = 1/2 WX

∴ SQ = 1/2 XY

- Lets calculate the length of the sides of Δ WXY

∵ QR = 1/2 WY

∵ QR = 2.93

∴ 2.93 = 1/2 WY ⇒ multiply both sides by 2

∴ WY = 5.86 cm

∵ RS = 1/2 WX

∵ RS = 2.04

∴ 2.04 = 1/2 WX ⇒ multiply both sides by 2

∴ WX = 4.08 cm

∵ SQ = 1/2 XY

∵ SQ = 2.28

∴ 2.28 = 1/2 XY ⇒ multiply both sides by 2

∴ XY = 4.56 cm

- Lets find the perimeter of Δ WXY

∵ The perimeter of Δ WXY = WX + XY + YW

∴ The perimeter of Δ WXY = 5.86 + 4.08 + 4.56 = 14.50

* The perimeter of Δ WXY is 14.50 cm

State the property that justifies the statement: If 4x + 9 = 15 and X=2y + 1,

GREYUIT [131]

Answer:

Substitution property of equality

Step-by-step explanation:

Given

$4x + 9 = 15$ and $x = 2y + 1$

Then

$4(2y + 1) + 9 = 15$

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If $a = b$ then $b = a$

In other words, both can replace one another.

So if $x = 2y + 1$ , then 2y + 1 can be substituted for x in $4x + 9 = 15$

So:

$4x + 9 = 15$ becomes

$4(2y + 1) + 9 = 15$

<em>Hence, it is substitution property of equality</em>
