How do you solve for problems like this? I know they have to add up to 180.
2 answers:
You already know the sum of the measures of the interior angles of a triangle add up to 180 degrees, so make all the angles add up to 180 in an equation.
(3x + 4) + (x + 8) + (2x) = 180
Combine like terms.
6x + 12 = 180
Subtract 12 from both sides.
6x = 168
Divide both sides by 6.
X = 28. Hope I was able to help

Answer:
x=-8 OR X=2
Step-by-step explanation:
X²+6X-6=10
X²+6X-16=0
X²+8X-2X-16
X(X+8)-2(X+8)
X+8=0 X-2=0
X=-8 OR X=2
