In a triangle, the sum of the interior angles is 180.
So, you have

Plug the values for angles A and C:

Answer:
4x - 3y -18 = 0 or y = 4x/3 - 6
Step-by-step explanation:
We will have to find the slope of the line first
The formula for slope:

The standard form of equation of a line is:
y = mx + b
We know m,
So the equation will be:

We have to find the value of b, for that we will put any one of the point in the equation
So, putting (6,2)
2 = 4/3 * 6 + b
2 = 8 +b
b = -6
Putting the value of m and b in the standard form of equation of line,
..
Answer:
x = 12
Step-by-step explanation:
The midsegment VY is half the sum of the parallel bases , that is
VY =
, then
3x + 18 =
(x + 96) ← multiply both sides by 2 to clear the fraction
6x + 36 = x + 96 ( subtract x from both sides )
5x + 36 = 96 ( subtract 36 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12
Answer:
5x+4
Step-by-step explanation:
6x+8-x-4
5x+4
50% is just half of the price. you could also times the original price by 1/2 and get the same answer.
