PLEASE HELP FAST!!!
Z is in the interior of ∠GHI. m∠GHI = 170, m∠GHZ = 3s - 5, and m∠ZHI = 2s + 25.


1. What is the value of s?


2. What are m∠GHZ and m∠ZHI??

Sagot :

[tex]\\ \sf\longmapsto 3s-5+2s+25=170[/tex]

[tex]\\ \sf\longmapsto 5s+20=170[/tex]

[tex]\\ \sf\longmapsto 5s=170-20[/tex]

[tex]\\ \sf\longmapsto 5s=150[/tex]

[tex]\\ \sf\longmapsto s=30[/tex]

  • m<GHZ=3(30)-5=90-5=85
  • m<ZHI=2(30)+25=60+25=85
