10. WHAT is any trapezoid. A straight line

Svetradugi [14.3K]

(a) ET = 18 and WE = 12

(b) FA = 16/3

HF = 8/3

ET = 8

WE = 4

Explanation:

WT = 30 ( WE + ET = 30)

WE = 30 - ET

2FA = 3HF

FA = 3/2HF

WE =?, ET = ?

Line WH, EF and TA are parallel to each other.

(a)

ΔWTA and ΔWHA are congruent to each other

Therefore, by congruency

$\frac{WE}{ET} = \frac{HF}{FA}$

So,

30 - ET/ ET = HF / 3/2HF

30 - ET / ET = 2HF / 3HF

30 - ET / ET = 2/3

On solving the above equation we get, ET = 18

WE = 30 - ET

WE = 30 - 18 = 12

Therefore, ET = 18 and WE = 12

(b)

HA = 8 ( HF + FA = 8)

HF = 8 - FA

WT = 12 ( WE + ET = 12 )

WE = 12 - ET

GA = 2WG

HF, WA, WE, ET = ?

ΔWHA and ΔGFA are congruent

So,

$\frac{HF}{FA} = \frac{WG}{GA}$

8 - FA / FA = WG / 2 WG

On solving the above equation we get,

FA = 16/3

HF + FA = 8

HF + 16/3 = 8

HF = 8/3

ΔWTA and ΔWEG are congruent

So,

$\frac{WE}{ET} = \frac{WG}{GA}$

12 - ET / ET = WG / 2WG

On solving the above equation, ET = 8

WE = 12 - ET

WE = 12 - 8

WE = 4

Therefore, FA = 16/3

HF = 8/3

ET = 8

WE = 4

hram777 [196]

Answer:

x+4≤13

just analyze the words carefully and their meanings, ex.: no more than = ≤

if you wish for the answer to this inequality:

Mr. Hansen baked 1,692 chocolate cookies he

Sav [38]

Answer:

Mr.Riley collected $376.

Step-by-step explanation:
First it says there are 1692 cookies and 36 boxes. When you put 1692 cookies into 36 boxes its the same thing as 1692 divided by 36 which is 47.
Then it says each box cost $8. So there are 47 cookies in 36 boxes and each box cost $8 which is the same as multiplying 47 by 8 which is $376.
