Question

100Points! show work

Answer 1

Using angle sum property

`\\ \sf\longmapsto x+43+73+70=180`

`\\ \sf\longmapsto x+43+143=180`

`\\ \sf\longmapsto x+186=180`

`\\ \sf\longmapsto x=180-186`

`\\ \sf\longmapsto x=-6`

Option C is correct

Answer 2

Sum of angles of any triangle is 180°

• x+43+73+70=180
• x+186=180
• x=180-186
• x=-6

Option C
