Question

please answer for this question

Answer 1

Answer:

Sum of outer angles of any polygon is 360°

that is. 89+92+20+85+x=360°

286+x =360°

x=360-286

x=74°

Answer 2

Answer:

x=74 degree

Step-by-step explanation:

so to answer this question you must know two points

1) sum of angles of pentagon = 540 degree

2) sum of angles in a straight line is 180 degree

now you have to just apply these points and u will have tha answer

1 st angle = 180 - 89 = 91 degree (using point 2)

2 nd angle = 180  - 92 = 88 degree (using point 2)

3 rd angle = 180 - 20 = 160 degree (using point 2)

4 th angle= 180 - 85 =  95 degree (using point 2)

5 th angle = 540 - ( 91 + 88+160+95) (using point 1)

                = 540 - 434

                = 106 degrees

now

x + 106 = 180 ( (using point 2)

x =  74 degree

hope it helps
