\sf{\bold{\green{\underline{\underline{Given}}}}}

⠀⠀⠀⠀

  • AD = 24cm
  • DB = 25 cm
<h3>______________________</h3>

\sf{\bold{\green{\underline{\underline{To\:Find}}}}}

⠀⠀⠀⠀

  • AB = d = ??
<h3>______________________</h3>

\sf{\bold{\green{\underline{\underline{Solution}}}}}

⠀⠀⠀⠀

Using Pythagoras theorem ;

⠀⠀⠀⠀

\sf{\red{\boxed{\bold{( hypotenuse )^2 = ( base )^2 + ( height )^2 }}}}

⠀⠀

First , lets understand the concept ;

⠀⠀

What is Pythagoras theorem ??

⠀⠀⠀⠀

  • In Pythagoras theorem the square of hypotenuse is equal to the square of base in the square of corresponding height when one angle is 90° .

⠀⠀⠀⠀

What is hypotenuse ?

⠀⠀⠀⠀

  • The side in the front of right angle is known as hypotenuse .

⠀⠀⠀⠀

In the given Δ ;

⠀⠀⠀⠀

Hypotenuse = DB = 25 cm

⠀⠀

<u>A</u><u>c</u><u>c</u><u>.</u><u> </u><u>t</u><u>o</u><u> </u><u>t</u><u>h</u><u>e</u><u> </u><u>f</u><u>o</u><u>r</u><u>m</u><u>u</u><u>l</u><u>a</u><u>e</u><u> </u><u>;</u>

⠀⠀⠀⠀

➠ 25² = 24² + d²

⠀⠀⠀⠀

➠ d² = 25 ² - 24 ²

⠀

➠ d² = 625 - 576

⠀⠀⠀⠀

➠ d² = 49

⠀

➠ d = √49

⠀⠀⠀⠀

➠d = 7cm

⠀⠀⠀⠀

<h3>______________________</h3>

Find the height of the tree to the nearest foot
poizon [28]
Looking at the triangle, we see that the angle 29.7 deg and the "adjacent side" length 20 ft are given.  Our job is to find the "opposite side," which is the height of the tree.

Write out the tangent function:    tan 29.7 deg = opp side  /  adj side

Then tan 29.7 deg = (opp side) / (20 ft).

Solving for the length of the opp side:

opp side = (20 ft)(0.57) = 11.41 feet.  This is also the height of the tree.
