Answer:
x=38
Step-by-step explanation:
the angles of any triangle always equals 180
so to find x we set up an equation like this: (2x+8)+(2x-18)+X=180
calculate to find x
Combine like terms: (2x+2x+x)+(8+−18)=180
2x+2x+x=5x
8+(-18)=-10
now we have 5x+(-10)=180
Add 10 to 180, then divide 190 by 5.
180+10=190/5=38
x=38
to find the measures put 34 into the angle equations
2(38)-8=58
2(38)+18=84
x=38
