Answer:
Step-by-step explanation:
always the vertically opposite angles are equal so
opposite angle of 120 is also equal to 120
therefore,
the sum of all angles in a quadrilateral = 360
angle a +angle b+angle c+angle d=360
120+70+x+x=360
190+2x=360
2x=360-190{Transposing 190 from LHS to RHS}
2x=170
x=170/2{Transposing 2 from LHS to RHS...so,it becomes division}
x=85
therefore the value of x is 85
