${\tt{\red{\underline{\large{Given}}}}}$

• A ∆ ABD
• AB=AD

${\sf{\green{\underline{\large{To\:find}}}}}$

• Value of x

${\sf{\pink{\underline{\Large{Explanation}}}}}$

Here in ∆ ABD

ACB + ACD = 180 (linear pair)

=>75° + ACD =180°

=> ACD = 180° - 75°

=>ACD = 105°

In ∆ ACD

• Sum of angles of ∆ be 180°

ACD + CAD + ADC = 180°

=>20° + 105° + ADC =180°

=>125° + ADC = 180°

=>ADC = 180°-125°

=> ADC = 55°

AB = AD

ABC = ADC

X=55°
