\\ \sf\longmapsto tan40=\dfrac{P}{430}

\\ \sf\longmapsto 0.83=\dfrac{P}{430}

\\ \sf\longmapsto P=430(0.83)

\\ \sf\longmapsto P\approx361m

  • P=Height of tower

Answer:

\displaystyle 361\:m.

Step-by-step explanation:

You would set your proportion up as so:

\displaystyle \frac{430}{h} = cot\:40° → 430 = hcot\: 40° → \frac{430}{cot\: 40°} = h → 360,8128414... = h \\ \\ 361 ≈ h

So, the height of the clock tower is <em>approximately</em><em> </em>361 metres.

How can I solve -4x+y=29
vlada-n [284]

Answer:

Step-by-step explanation:

What variable are you solving for?

-4x+y=29

y=29-(-4x)

y=29+4x

y=4x+29

----------------

-4x=29-y

-4x=-y+29

x=1/4y+29/-4

y=1/4y-29/4

Answer:

The answer should be 3 cubic cm

Step-by-step explanation:

First you have to get the area of the right triangle base 1/2 bh. That would be 2x3/2=3

To find volume, you plug the area in the volume formula

v=1/3 ah

v=1/3 (3)(3)

1/3(9) would be 3 cubic cm
