Answer:

  • 40°

Step-by-step explanation:

The triangle has two internal angles of 70° and one angle of x°.

Considering the sum of angles is 180°, find the value of x:

  • x + 2*70 = 180
  • x + 140 = 180
  • x = 40

The adjacent angles of similar sides are equal

[tex]\\ \tt\longmapsto x+2(70)=180[/tex]

[tex]\\ \tt\longmapsto x+140=180[/tex]

[tex]\\ \tt\longmapsto x=40[/tex]
