Answer:

x = 3.2

Step-by-step explanation:

Since, intercepts made by parallel lines on the transversals are in proportion.

\therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)

AB = BC.... (given)

\implies \frac{AB}{BC} = 1..... (2)

From equations (1) & (2)

1 =\frac{EF}{FG}

{FG}={EF}

Therefore,

7x - 9 = 2x + 7

7x - 2x = 9 + 7

5x = 16

x = 16/5

x = 3.2

Answer:

BC = 8 \sqrt{2}

Step-by-step explanation:

\sin(45)  =  \frac{opposite}{hypotenuse}

\sin(45)  =  \frac{8}{BC}

(BC) \sin(45)  =  \frac{8}{x} (BC)

(BC) \sin(45)  = 8

\frac{(BC) \sin(45) }{ \sin(45) }  =  \frac{8}{ \sin(45) }

BC =  \frac{8}{ \sin(45) }

BC = 8 \sqrt{2}

FromTheMoon [43]
11 meters because if you do 14.3-5.8=8.5 then it said he went up so now you do 8.5+3.2=11.7 but instead of rounding up she rounded down (I think that’s the answer)
