Question

find the angle measure of X in the following figure​

Answer 1

Answer:

140

Step-by-step explanation:

The fourth angle would be 90 as it's forming a linear pair with the other angle.

The sum of all the interior angels of a quadrilateral is 360.

thus

60+70+90+x=360

x= 360-60+70+90

x =140

Answer 2

Answer:

140 degree as if we add the value 70 plus 60 plus 90 we get 220 then subtract 360 with 220 we get 140
