Question

find the x of both the sum ​

and I will mark brain list

Answer 1

Step-by-step explanation:

Case 1 :

sum of the interior angles in quadrilateral is 360°

therefore,

=> 90° + 75° + 63° + x = 360°

=> x = 360° - ( 90° + 75° + 63°)

=> x = 132°

Case 2 :

same reason as case 1

=> 33° + 140° + x + 2x + (x + 75°) = 360°

=> 4x = 112°

=> x = 28°

So, 2x = 56° & (x + 75°) = 103°

Answer 2

Answer:

a)12

b)A=87

C=24

B=113

Step-by-step explanation:

75-63=12

12+75=87

33-140=113

2(12)=24
