plzzz answer fastly guys....​

Answer 1

Answer:

ABCD is a quadrilateral in which angle A=3x+20°,Angle B=5x+3°,Angle C=3x+10°,Angle D =x+3°.The value of x=_27°_

Answer 2

Answer:

x=12

Step-by-step explanation:

the sum of all angles in triangle is 180 degree

3x+20°+5x+3°+3x+10°+x+3°=180°

12x+36°=180

12x=180°-36°

12x=144

x=144/12

x=12
