Question

find the angle measure x in the following figure ​

Answer 1

Answer:

OK we should apply the theoram

here we should add all which is equal to 540 degree. ext angle D =90degree (linear pair) similarly to ext angle B

60+90+90+70+x=540

310+x=540

x=230degree.

Answer 2

Answer:

x = 120°

Step-by-step explanation:

sum of all the exterior angles= 360°

60° + 90° + 70° + x + 90° = 360°

240° + x = 360°

x = 360° - 240°

x = 120°
