Answer:

x = 5

Step-by-step explanation:

The interior angles of a triangle always have to add up to 180 degrees.

This means you can form an equation with the three angles you have:

(10x - 4) + (8x + 3) + 91 = 180

Then, solve:

[tex]10x-4+8x+3+91=180[/tex]

combine like terms

[tex]18x+90=180[/tex]

subtract 90 from both sides

[tex]18x = 90[/tex]

divide both sides by 18

[tex]x = 5[/tex]
