Answer 1

Answer: 57. 70 degrees ==> D

58. 80 degrees

Explanation:

57. IHM=9x+7

MHG=16x-2

IHG=180

IHM+MHG=IHG

9x+7+16x-2=180

25x+5=180

25x=175

x=7

IHM=9(7)+7

IHM=63+7

IHM=70 degrees ==> D

58. LMZ=x+82

LMN=162

ZMN=x+84

LMN=LMZ+ZMN

162=x+82+x+84

162=2x+166

2x=-4

x=-2

LMZ=-2+82

LMZ=80 degrees
