Answer:

I think this can help you!!!

The value of X is 12.

Answer 2

Answer:

10x- 16 = 3x+ 20 + 4x (Exterior angle of a triangle is equal to the sum of opposite interior angles )

10x-7x = 20 + 16

3x = 36

x = 12

Angles are :

angle A = 3(12)+20= 56

angle B = 4(12) = 48

angle DBC = 10(12)-16 = 104
