Question

find the angle measure X in the following figure​

Answer 1

Answer:

110

Step-by-step explanation:

as we know that the sum of angle of polygon

= (n-1)*180°

as it is a pentagon therefore

sum of angle = (5-1)*180

= 540

in this figure four angles are given let take fifth angle be =180-x because of the property sum of interior and exterior angle

there fore

we can write

50+90+110+2x+180-x=540

430+x=540

x=540-430

x=110

hence x=110
