\tt{ Hey \: there , \: Mr.Panda \: ! } ;)

♨\large{ \tt{ E \: X \: P \: L \: A \: N \: A \: T \: I\: O \: N}}:

⤻ Before solving the given question , you should know the answer of these questions :

✺How do you find the hypotenuse , perpendicular and base when the angle ( \theta \: , \alpha  \:  ,\beta ) is given ?

⇾ The longest side , which is the opposite side of right angle is the hypotenuse ( h ). There are two other sides , the opposite and the adjacent. The naming of these sides depends upon which angle is involved. The opposite is the side opposite the angle involved and it is called the perpendicular ( p ) . The adjacent us the side next to the angle involved ( buy not the hypotenuse ) and it is called the base ( b ).

☄ \large{ \tt{REMEMBER}} :

  • \bf{ \sin \theta =  \frac{opposite}{hypotenuse}  =  \frac{perpendicular}{hypotenuse}  }

  • \bf{ \cos\theta =  \frac{adjacent}{hypotenuse}  =  \frac{base}{hypotenuse}  }

  • \bf{ \tan \theta =  \frac{opposite}{adjacent}  =  \frac{perpendicular}{base}  }

In the above cases , \theta is taken as the angle of reference.

♪ Our Q/A part ends up here! Let's start solving the question :

❈ \large{ \tt{GIVEN}} :

  • Perpendicular ( p ) = ? , Hypotenuse ( h ) = 18 & base ( b ) = 16

✧ \large{ \tt{TO \: FIND} : }

  • Value of tan \theta

✎ \large{ \tt{SOLUTION}} :

Firstly , Finding the value of perpendicular ( p ) using Pythagoras theorem :

❃ \boxed{ \sf{ {h}^{2}  =  {p}^{2}  +  {b}^{2} }} [ Pythagoras theorem ]

\large{ ⇢ \sf{p}^{2}  +  {b}^{2}  =  {h}^{2} }

\large{⇢ \sf{ {p}^{2}  =  {h}^{2}  -  {b}^{2} }}

\large{ ⇢\sf{ {p}^{2}  =  {18}^{2}  -  {16}^{2} }}

\large{⇢ \sf{ {p}^{2}  = 324  - 256}}

\large{⇢ \sf{ {p}^{2}  = 68}}

\large{⇢ \sf{p =  \sqrt{68}}}

\large{ ⇢\sf{p =  \boxed{ \tt{2 \sqrt{17}}} }}

Okey, We found out the perpendicular i.e \tt{2 \sqrt{17}} . Now , We know :

❊ \large{ \sf{ \tan \theta} =  \frac{perpendicular}{base} }

\large {\tt{↬ \: tan \theta =  \frac{2 \sqrt{17} }{16}}}

\large{ \tt{ ↬ tan  \theta =  \frac{ \cancel{2} \:  \sqrt{17} }{ \cancel{16} \:  \: 8} }}

\large{ \tt{ ↬ \boxed{ \tt{tan \theta =  \frac{ \sqrt{17} }{8}}}}}

⟿ \boxed{ \boxed{ \tt{OUR\: FINAL \: ANSWER : \boxed{ \underline{ \bf{ \frac{ \sqrt{17} }{8}}}}}}}

۵ Yay! We're done!

♕ \large\tt{RULE \: OF \:SUCCESS }:

Is X=[−14−32] the inverse of A=[15−25310−110]?
Elis [28]

The product of the matrices is an identity matrix. Therefore, X and A are inverse of each other.

The matrices are given as:

X = \left[\begin{array}{cc}-1&-3\\4&2\end{array}\right]

A = \left[\begin{array}{cc}\frac 15&\frac 3{10}\\-\frac 25 &-\frac 1{10}\end{array}\right]

To check the matrices are inverse, we calculate their products.

A \times X =  \left[\begin{array}{cc}\frac 15&\frac 3{10}\\-\frac 25 &-\frac 1{10}\end{array}\right] \times \left[\begin{array}{cc}-1&-3\\4&2\end{array}\right]

Multiply the rows of A by the column of X.

This gives

A \times X =  \left[\begin{array}{cc}\frac 15 \times -1 + \frac{3}{10} \times 4&\frac 15 \times -3 + \frac{3}{10} \times 2\\ -\frac 25 \times -1 - \frac{1}{10} \times 4&-\frac 25 \times -3 + -\frac{1}{10} \times 2\end{array}\right]

A \times X = \left[\begin{array}{cc}1&0\\0&1\end{array}\right]

The product of  A and X is an identity matrix.

This means that; both matrix are inverse of each other
