Answer:

∠AGE = 126°, ∠GEF = 36° और ∠FGE = 54∘

Step-by-step explanation:

हल :  

दिया है :  ∠GED = 126°

∠AGE = ∠GED = 126°

[एकांतर अंतः कोण]

∴ ∠AGE = 126°

∠GED =∠GEF +∠FED

126° = ∠GEF + 90°

(दिया है : EF⊥CD)

⇒∠GEF = 126° − 90°

⇒∠GEF = 36°

तथा ∠CEG + ∠GED = 180°

[रेखीय युग्म अभिगृहीत]

⇒∠CEG + 126° = 180°

[दिया है :  ∠GED = 126°]

⇒∠CEG = 180 ° − 126°

⇒∠CEG = 54°

∠FGE =∠CEG = 54∘      

[एकांतर अंतः कोण]

∴ ∠FGE = 54∘

अतः, ∠AGE = 126°, ∠GEF = 36° और ∠FGE = 54∘

आशा है कि यह उत्तर आपकी मदद करेगा।

❣️❣️\textbf{\underline{\underline{\large{\pink{Step by step Explanation:-}}}}}

\mathcal{\underline{Given,,}}

\mathtt{AB \parallel CD}, \mathtt{EF \perp CD}

and \mathtt{\angle GED = 126°}

\mathcal{\underline{Hence,,}}

\mathtt{\angle AGE =\angle GED}

\textit{(Alternate angle)}

\mathtt{\implies{\angle AGE =126°}}

\mathcal{\underline{and,,}}

\mathtt{\angle GEF+\angle FED =\angle GED}

\mathtt{\implies{\angle GEF+90°=126°}}

\mathrm{(Given,,AB \parallel CD,, Hence,,\angle FED =90°)}

\mathtt{\implies{\angle GEF=126°-90°}}

\mathtt{\implies{\angle GEF=36°}}

\mathcal{\underline{since,,}}

\mathtt{\angle GEC+\angle GED =180°}

\mathtt{\implies{\angle GEC+126° =180°}}

\mathrm{(Given,,\angle GED =126°)}

\mathtt{\implies{\angle GEC=180°-126°}}

\mathtt{\implies{\angle GEC=54°}}

\mathcal{\underline{So,,}}

\mathtt{\angle FGE=\angle GEC}

\textit{(Alternate angle)}

\mathtt{\implies{\angle FGE=\angle 54°}}

\mathcal{\underline{Hence,,}}

\mathtt{\implies{\angle AGE =126°}}

\mathtt{\implies{\angle GEF=36°}}

\mathtt{\implies{\angle FGE=54° }}
