This is how you do it:
x+95=3x-35
x + 130 = 3x (add 35 to both sides)
130=2x (take away x from both sides)
x = 65 (divide everything by two)
<span>Given cotA + cotB + cotC = sqrt3
to prove triangle ABC is equilateral
we prove this by assuming ABC to be equialteral and establishing the truth
of the statement cotA + cotB + cotC =sqrt3
since ABC is equialteral angleA=angleB=angleC=60 degrees
cotA=cotB=CotC = cot60= 1/sqrt3
therefore cotA + cotB + cotC = 1/sqrt3 + 1/sqrt3 + 1/sqrt3
=3/sqrt3
=sqrt3 which is equal to the RHS ( right hand side) of the expression
hence our assumption that ABC is equilateral is true</span>
Sorry for the late response
(bigger number - smaller number) divided by original number
(251 - 248) / 248
3 / 248 Divide to make this a decimal
0.0120967741... round it
0.012 change into percent
The rate of change is 1.2%
hope this helps!
<span>A) 1.5 percent.
