<h3><u>Given</u>: </h3>

  • Base of traingle = 4cm
  • Area of Traingle = 20cm^2

~

<h3><u>Need to Find?</u></h3>

  • Height of Traingle

~

<h2><u>Solution: </u></h2>

  • Let Height (H) of traingle be <u>H cm</u>

~

<u>Using formula:</u>

  • \underline{ \boxed { \textbf{ \textsf{Area  \: of  \: Traingle = 1/2 × B × H   }}}}

~

<u>Putting values in the formula:</u>

\longrightarrow \sf 20 = 1/2 × 4 × H

\longrightarrow \sf 20= 2 × H

\longrightarrow \sf 20/2 = H

\longrightarrow \sf H = 10cm

~

\therefore <u>Height of Traingle is 10cm</u>

Suppose we have a right triangle with legs of length a and b and hypotenuse of length c. Suppose b=3 and c=5. Then a= , For the
ANTONII [103]

Answer:

Length of right-angle  triangle 'a' = 4

b)

<u><em></em></u>sin(A) = \frac{opposite side}{Hypotenuse} = \frac{a}{c} = \frac{4}{5}<u><em></em></u>

<u><em></em></u>cos(A) = \frac{Adjacent side}{Hypotenuse} = \frac{b}{c} = \frac{3}{5}<u><em></em></u>

<u><em></em></u>tan(A) = \frac{opposite side}{Adjacent side} = \frac{a}{b} = \frac{4}{3}<u><em></em></u>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given  b = 3 and hypotenuse c = 5

Given ΔABC  is a right angle triangle

By using pythagoras theorem

        c² = a² + b²

  ⇒ a² = c² - b²

 ⇒  a² = 5²-3²

          =25 - 9

      a² = 16

⇒   a = √16 = 4

The sides of right angle triangle  a = 4 ,b = 3 and c = 5

<u><em>Step(ii):-</em></u>

<u><em></em></u>sin(A) = \frac{opposite side}{Hypotenuse} = \frac{a}{c} = \frac{4}{5}<u><em></em></u>

<u><em></em></u>cos(A) = \frac{Adjacent side}{Hypotenuse} = \frac{b}{c} = \frac{3}{5}<u><em></em></u>

<u><em></em></u>tan(A) = \frac{opposite side}{Adjacent side} = \frac{a}{b} = \frac{4}{3}<u><em></em></u>
