Question

Find X for brainiest

Answer 1

Answer:

136°

Step-by-step explanation:

In quadrilateral ABCD,

$m\angle A = 180\degree - 107\degree = 73\degree$(Angles in linear pair)

$m\angle B = 61\degree$(Vertical Angles)

$m\angle C= 90\degree$(Given)

$m\angle A +m\angle B+m\angle C+m\angle D= 360\degree$(Interior angle sum postulate of a quadrilateral)

$73\degree +61\degree+90\degree+x= 360\degree$

$224\degree+x= 360\degree$

$x= 360\degree-224\degree$

$x= 136\degree$
