Question

The sum of two angles 5x - 75 degree and 4 x + 66 degrees is 180 degree find the value of x

Answer 1

Correct Question :

• The sum of two angles is ( 5x - 75 ) ° and ( 4x + 66 )° is 180°. Find the value of x

$\textbf{\underline{\underline{Step-By-Step Explanation}}}$

$\sf\blue{Given :}$

• Two angles are : ( 5x - 75 ) and (4x + 66)
• Sum of two angles = 180°

$\sf\blue{To\: Find :}$

• Value of x

$\sf\blue{Solution :}$

5x - 75 + 4x + 66 = 180° ( sum = 180° )

----> 5x + 4x - 9 = 180°

----> 9x - 9 = 180°

----> 9x = 180° + 9

----> 9x = 189

---> x = $\dfrac {189}{9}$

•°• x = 21

Answer: The value of x is 21
