Answer 2

Answer:

the value of x is 140°

Step-by-step explanation:

Sum of all angles of a pentagon is 540°.

180°-70°= 110° and 180°-60°= 120° since they are supplementary angles.

Now, 30°+120°+110°+x+x= 540°

or, 260°+2x= 540°

or, 2x=540°-260°

or, 2x= 280°

or, x = 280/2

therefore, x = 140° Answer.
