In the figure, we can see that DC and FE are two lines parallel to each other and AB is acting as a transversal.

Then, ∠DZQ + ∠FQZ = 180°

(Interior angles on the same side of the transversal are supplementary i.e. they add upto 180°)

GiveN:

  • ∠DZQ = 2x + 6°
  • ∠FQZ = 3x + 54°

Then,

⇒ ∠DZQ + ∠FQZ = 180°

⇒ 2x + 6° + 3x + 54° = 180°

⇒ 5x + 60° = 180°

⇒ 5x = 120°

⇒ x = 120° / 5

⇒ x = 24°

Hence,

  • The required value of x is 24°

When two parallel lines are intersected by a transversal:

  • Alternate interior and Alternate exterior angles are equal.
  • Corresponding angles are equal.
  • Vertically opposite angles are equal.
  • The interior/exterior angles on the same side of the transversal are supplementary.

  • DZQ = 2x + 6 °
  • FQZ = 3x + 54°

{\underline{\underline{\sf{\large{\pink{\bigstar{\: To \:  find  : }}}}}}}

  • Value of x :-

{\Large{\underline{\underline{\sf{\large{\red{\bigstar{\: Solution : }}}}}}}}

Here the concept of the question is that Two parallel lines are given CD || EF and AB is the transversal in which two angles are made on the same side of interior of the transversal and we know that Angles made on the interior same side of the transversal is 180°. So, here we can write this as.

{\mathtt{\implies{ ∠DZQ + ∠FQZ = 180°}}}

{\mathtt{\implies{2x + 6° + 3x + 54° = 180°}}}

{\mathtt{\implies{2x + 3x + 6° + 54° = 180°}}}

{\mathtt{\implies{5x + 60° = 180° }}}

{\mathtt{\implies{5x = 180° - 60°}}}

{\mathtt{\implies{5x = 120°}}}

 \\ {\mathtt{\implies{x =  \frac{120}{5} }}}

 \large{ \orange{ \boxed{ \boxed{\mathtt{\implies{ \blue{x = 24 \degree}}}}}}}

So, Value of x is 24°.

\documentclass{article} \begin{document} \begin{table}[h!] \begin{center} \caption{Your first table.} \label{tab:table1} \begin{tabular}{l|c|r} % <-- Alignments: 1st column left, 2nd middle and 3rd right, with vertical lines in between \textbf{Value 1} & \textbf{Value 2} & \textbf{Value 3}\\ $\alpha$ & $\beta$ & $\gamma$ \\ \hline 1 & 1110.1 & a\\ 2 & 10.1 & b\\ 3 & 23.113231 & c\\ \end{tabular} \end{center} \end{table} \end{document}

For more finding all angles.

First angle:-

》2x + 6 °

》2(24) + 6

54°

So, Value of first Angle is 54°

☆Second Angle :-

3x + 54°

3 × 24 + 54 °

126°

So, Value of second angle is 126°.

VERIFICATION:-

》126° + 54° = 180°

》180° = 180°

》LHS = RHS

So, our answer 24° is correct answer.
