Question

Find 'x' in the following ​

Answer 1

First we have to find angle D

As it is a quadrilateral

$\\ \sf\longmapsto$

$\\ \sf\longmapsto 45+50+35+$

$\\ \sf\longmapsto 130+$

$\\ \sf\longmapsto$

$\\ \sf\longmapsto$

Now

$\\ \sf\longmapsto$

$\\ \sf\longmapsto x+230=360$

$\\ \sf\longmapsto x=360-230$

$\\ \sf\longmapsto x=130°$

Answer 2

Answer:

x = 130

Step-by-step explanation:

Sum of all the angle of quadrilateral = 360°

50 + 45 + 35 + ∠ADC = 360

                130 + ∠ADC = 360

                         ∠ADC = 360 - 130

                         ∠ADC = 230

x = Reflex ∠ADC

  = 360 - 230

  = 130
