Step-by-step explanation:

  • 8x+5+18x+45=180°{ sum of angle of triangle}
  • 26x+50=180°
  • 26x=180-50
  • x=130/26
  • x=5°

measure of angle of triangle=8x+5

Answer:

Option D is correct

Step-by-step explanation:

Hint :

Sum of angles in triangle= 180°

Simplify:

[tex](8x+5)+18x+45=180[/tex]

[tex]26x+50=180[/tex]

[tex]26x=180−50[/tex]

[tex]26x=130[/tex]

[tex]x = \frac{130}{26} [/tex]

[tex]x = 5[/tex]

Measure of angle : [tex]18x+5 = 18(5)+5 \\ = 40+5 \\ =45 [/tex]

[tex]18x = x + 18 \\ = 5 + 18 \\ 23[/tex]

Hope it is helpful....
