pls answer its very urgent​

Answer 1

$\huge{\fcolorbox{maroon}{s} {\large{\fcolorbox{white}{mistyrose}{{\fcolorbox{gold} {White}{Solution}}}}}}$

We know that,

By angle sum property, the sum of all the angles in a quadrilateral is 360°

According to the figure,

$∠A + ∠B + ∠C + ∠D = 360°$

$= > \: 110 °+ 45° + 30 °+∠D = 360°$

$= > \: 185° + ∠D = 360°$

$= > \: ∠D = 360° - 185°$

$= > \: ∠D = 175°$

Therefore, the measure of the unknown angle is 175°.

Hope it helped you..

Thank you !!

Answer 2

Answer:

= 110 + 45 + 30 + D =360

= 185 + D = 360

= D = 360 - 185

= 175 ( sum of exterior angle are 360)
