Question

Find angle x in the following figure.
​

Answer 1

Answer:

30°

Step-by-step explanation:

100°= x+ 70°( exterior angle property )

100°= x+ 70°( exterior angle property )x= 30°

Answer 2

Answer:

So here is your answer and explanation

Step-by-step explanation:

70 degree is given then the lower left angle is 80 because 80 + 100 = 180 degree because that complete angle would make 180

so now we have 70 + 80 + x

150 + x = 180 (Because sum of all angles is 180 degree)

so, now 180-150 = 30

so x is 30 degree
