The perimeter of the triangle is 42. Find the length of all the sides.
iragen [17]
<h3>Given :-</h3>

  • Perimeter of triangle = 42

  • Side 1 of triangle = (x + 4)

  • Side 2 of triangle = (3x + 8)

  • Side 3 of triangle = (5x + 6)

<h3>To find:-</h3>

  • Length of sides

<h3>Explanation:</h3>

So to find length of sides we have to find the value of x.We can find value of x , by this formula:

\\  \\

\bigstar \boxed{ \rm perimeter \: of \triangle \:  = side_1 + side_2 + side_3}

\\  \\

So:-

\\

\dashrightarrow \tt perimeter \: of \triangle \:  = side_1 + side_2 + side_3 \\

\\  \\

\dashrightarrow \tt 42  = (x + 4) + (3x + 8)+( 5x + 6) \\

\\  \\

\dashrightarrow \tt 42  = x + 4+ 3x + 8+5x + 6 \\

\\  \\

\dashrightarrow \tt 42  = x + 3x+5x+ 4 + 8 + 6 \\

\\  \\

\dashrightarrow \tt 42  = 9x+ 4 + 8 + 6 \\

\\  \\

\dashrightarrow \tt 42  = 9x+ 18\\

\\  \\

\dashrightarrow \tt 42  - 18 = 9x \\

\\  \\

\dashrightarrow \tt 24 = 9x \\

\\  \\

\dashrightarrow \tt  9x = 24 \\

\\  \\

\dashrightarrow \tt  x = \dfrac{24}{9}  \\

\\  \\

\dashrightarrow \bf  x =2.67 \{approx \}\\

\\  \\

  • Side 1 of triangle = (x + 4)
  • Side 1 of triangle =2.67 + 4
  • Side 1 of triangle = 6.67

  • Side 2 of triangle = 3x + 8
  • Side 2 of triangle = 3 × 6.67 + 8
  • Side 2 of triangle = 20.01 + 8
  • Side 2 of triangle = 28.01

  • Side 3 of triangle = 5x + 6
  • Side 3 of triangle = 5 × 2.67 + 6
  • Side 3 of triangle = 13.35 + 6
  • Side 3 of triangle = 19.35

Solving a _____ is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side length
Ray Of Light [21]
ANSWER

C) Triangle

EXPLANATION

Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.

We use the sine rule and cosine rule to find the missing sides and angles.

If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.
