Mathematics

Tomtit [17]4 years ago
7 0
Well it's easier to say the expanded version 8x-14
14 less than 8 times a number

But you could say the bracketed version in a strange way
7 less than 2 times a number all times 4

Find the value of cos J rounded to the nearest hundredth, if necessary.
WARRIOR [948]

\green{\huge{\red{\boxed{\green{\mathfrak{QUESTION}}}}}}

Find the value of cos J rounded to the nearest hundredth

\bold{ \red{\star{\blue{GIVEN }}}}

HYPOTHESES= 13

PERPENDICULAR= 12

BASE = ?

\bold{\blue{\star{\red{TO \:  \: FIND}}}}

\cos(j)  =  ?

\bold{  \green{ \star{ \orange{FORMULA \:  USED}}}}

  1. PYTHAGORAS THEROM
  2. \cos(j) =  \frac{ BASE}{HYPOTENUSE}

\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}

<h2>FOR BASE:- </h2>

{h}^{2}  =  {p}^{2}  +  {b}^{2}

{13}^{2}  =  {12}^{2}  +  {x}^{2}  \\ 169 - 144 =  {x}^{2}  \\ 25 =  {x}^{2}  \\  \sqrt{25}  = x \\ 5 = x = base

<h2>NOW :- </h2>

\cos(j) =  \frac{ BASE}{HYPOTENUSE}

\cos(j)  =  \frac{5}{13}  \\  \cos(j)  = 0.34

Is 26 a perfect square? explain.
Aloiza [94]
No because if you were to square it you would get 5.099 and a perfect square is when it is the same number times each other to get a number for example: the square root of 9 is 3 so 3 times 3 is 9. 
 
Hope that helps!
