Answer:
17
Step-by-step explanation:
This is an isosceles triangle. However, it doesn't really matter since ALL TRIANGLES HAVE A SUM OF 180 DEGREES.
Now that you know that, you can add up all of the angles and set it equal to 180.
[tex](x+17) + (6x+10) + (4x-34)=180[/tex]
Now solve for x
[tex](x+17) + (6x+10) + (4x-34)=180\\11x-7=180\\11x=187\\x=17[/tex]
The value of x is 17.
