Left side:
x+x+x+1+1+1+1+1+1+1+1 = 3x + 8
Right side:
x+x+x+x++1+1+1+1+1+1
Left side = Right side to solve x
3x + 8 = 4x + 6
Subtract 4x from both sides
3x + 8 - 4x = 4x + 6 - 4x
Simplify
-x + 8 = 6
Subtract 8 from both sides
-x + 8 - 8 = 6 - 8
Simplify
-x = -2
Multiply both sides by (-1)
-x * (-1) = -2 * (-1)
Simplify
x = 2
Answer
C. x = 2
The answer to this question is 3
Answer:
y-3 = 4/7(x-7)
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1)
We know the slope (4/7)
and a point (7,3)
Lets substitute into the equation
y-3 = 4/7(x-7)
Because a triangle's angles need to equal 180, you can subtract 100(30+70) and you will get 80. So 80 will be your third angle.
