Since you need to dilate the scale factor by four, I am pretty sure you would just multiply each value by 4

19(4) = 76

16.5(4) = 66

27(4) = 108

21(4) = 84

16(4) 64

Hope this is what you were looking for and hope this is right...

Q.4.
Anuta_ua [19.1K]

Answer

<u>2</u><u>.</u><u>5</u><u>6</u><u>m</u>⠀

Step by Step explanation:

⠀

Let AC be the 7 meters high Flagstaff

And BC be the tower

⠀

Let the height of BC = x

The height of AB will be (x + 7)m

⠀

∠ADB = 45° and ∠CDB = 15°

(as given in the question)

⠀

<u>By</u><u> </u><u>using</u><u> </u><u>trigonometry</u><u> </u><u>formula</u>

\sf  \tan(A)  =  \frac{perpendicular}{base}

⠀

⠀

So tan 45 will be

\sf \implies \tan45{ \degree} =  \frac{AB}{BD}   \\  \\  \sf  \implies \tan45{ \degree} =  \frac{x + 7}{BD}   \\  \\  \sf \implies 1 =   \frac{x + 7}{BD}   \\  \\  \sf  \implies BD = (x + 7)m

⠀

⠀

And tan 15 will be

\sf \implies \tan15{ \degree} =  \frac{BC}{BD}  \\  \\  \sf  \implies   \tan15{ \degree} =  \frac{x}{BD}    \\  \\  \sf  \implies 0.2679 =  \frac{x}{BD}  \\  \\  \sf  \implies BD =  \frac{x}{0.2679} \\  \\  \sf \implies  BD = 3.7327x

⠀

⠀

Using both Values of BD to find x

⠀

\sf x + 7 = 3.7327x \\  \\  \sf 7 = 2.7327x \\  \\  \sf  \frac{7}{2.7327}  = x \\  \\  \sf  \boxed{2.56 = x}

<u>The</u><u> </u><u>height</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>tower</u><u> </u><u>is</u><u> </u><u>2</u><u>.</u><u>5</u><u>6</u><u>m</u>
