Answer 1

Answer:

14°

Step-by-step explanation:

Given :-

• They are forming a linear pair.
• The angles are :

➤ (6x - 40)°

➤ (5x + 9)°

➤ (3x + 15)°

To Find :-

• Value of x.

Solution :-

★ As they forming a linear pair so :

$\longrightarrow$ (6x - 40)° + (5x + 9)° + (3x + 15)° = 180°

$\longrightarrow$ 6x + 5x + 3x - 40 + 9 + 15 = 180°

$\longrightarrow$ 14x - 40 + 24 = 180°

$\longrightarrow$ 14x - 16 = 180°

$\longrightarrow$ 14x = 180 + 16

$\longrightarrow$ 14x = 196°

$\longrightarrow$ x = 196/14

$\longrightarrow$ x = 14°

Hence,

• Value of x is 14°

Answer 2

___________________

Given :-

• 1 angle = (6x - 40)°
• 2 angle = (5x + 9)°
• 3 angle = (3x + 15)°

To Find :-

• The value of x

Solution :-

~ We can see that there is a straight line being divided into 3 parts/angles. We also know that the straight line is 180° , so the 3 angles add up to 180° .

» Sum of the three angles = 180°

Finding the value of x :-

» (6x - 40)° + (5x + 9)° + (3x + 15)° = 180°

» (6x + 5x + 3x - 40 + 9 + 15)° = 180°

» (14x - 16 )° = 180°

» 14x = ( 180 + 16 )°

» 14x = 196°

» x = 196/14

» x = 14°

Therefore, the value of x is 14°

Verification :-

» Sum of the 3 angles = 180°

» (6x - 40)° + (5x + 9)° + (3x + 15)° = 180°

» (6×14 - 40)° + (5×14 + 9)° + (3×14 + 15)° = 180°

» (84 - 40)° + (70 + 9)° + (42 + 15)° = 180°

» ( 44 + 79 + 57 )° = 180°

» 180° = 180°

Hence, verified!
