Find the value of x and find the value of polygon JKLM​

  1.  (B)  73

  2. r = 15

Step-by-step explanation:

1. The sum of angles in a triangle is 180°.

  62° +45° +k° = 180

  k = 180 -107

  k = 73

__

2. The sum of exterior angles of any polygon is 360°.

  4r° +7r° +5r° +8r° = 360°

  24r = 360 . . . . . . . . . . . . . collect terms, divide by °

  r = 360/24 . . . . . divide by 24

  r = 15

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
