Answer 1

$⍟ \: \: \underline{ \red{ \rm SOLUTION \: \: : }}$

$\rm 5x - 75 + 4x + 66 = 180$

$\rm 9x - 9 = 180$

$\rm9x = 189$

$\rm x = \frac{189}{9}$

$\bf ⇒ x = 21 \degree$

Answer 2

Answer:

Correct Question :

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

Step-By-Step Explanation

Given:

Two angles are : ( 5x - 75 ) and (4x + 66)

Sum of two angles = 180°

ToFind:

Value of x

Solution:

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

----> 5x + 4x - 9 = 180°

----> 9x - 9 = 180°

----> 9x = 180° + 9

----> 9x = 189

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

9

189

•°• x = 21

Answer: The value of x is 21
