Answer 1

Using angle sum property

`\\ \sf\longmapsto 5x+19+8x-11+11x+4=180`

`\\ \sf\longmapsto 24x12=180`

`\\ \sf\longmapsto 24x=180-12=168`

`\\ \sf\longmapsto x=(168)/(24)`

`\\ \sf\longmapsto x=7`

• <1=11(7)+4=77+4=81[/tex]

Answer 2

x is 7 and m<1 is 99°

Explanation:

m<NMQ + m<MQN + m<QNM = 180°

`{ \sf{(5x + 19) + (8x - 11) + (11x + 4) = 180}} \\ { \sf{24x + 12 = 180}} \\ { \sf{24x = 168}} \\ { \sf{x = (168)/(24) }} \\ \\ { \sf{x = 7}}`

m<1 = 180° - (11x + 4)

m<1 = 180° - 81°

m<1 = 99°
