Question

Find the angle x...pls ​

Answer 1

Answer:

x=85

Step-by-step explanation:

Its a quadrilateral so all interior angles equal to 360

120+70+2x=360

2x=170

x=85

Answer 2

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
