8x^2-5x-2
method
open bracket
6x^2-2x-3+x^2-3x+1
collect like terms
6x^2+2x^2-3-3x+1
8x^2-3-3x+1
again collect like terms
8x^2-2x-3x-3+1
8x^2-5x-3+1. (-×-=+ addition but keeping sign minus
8x-5x-2. (-×+=-)
Answer:

since a whole circle is 360 degrees just subtract 259 from 360
Use pythagorean theorem
a^2+b^2=c^2
4^2+3^2=c^2
16+9=c^2
25=c^2
c=5
hope this helps!
Answer:
[See Below]
Step-by-step explanation:
✦ So it must add up to 360dg so add:
✧ 115dg + 85dg + 60dg = 260dg
✦ Now subtract:
✧ 360dg - 260dg = 100dg
So X would be 100 degrees.
