We know that the sum of the internal angles in each triangle is 180°.
Therefore we have the equation:
substitute and solve:
We have
substitute the value of x to the expression:
Answer: m∠N = 42 degrees
Answer:
x = -6
Step-by-step explanation:
I'm assuming you're solving for x
3/4 (4x + 8) = -12
you distribute the 3/4 to 4x and 8 so
3/4 times 4x = 3x
3/4 times 8 = 6
now looks like
3x + 6 = -12
3x = -12 - 6
3x = -18
x = -6
Polygon area = n*side length^2 / [4*tan(180/n)]
side length^2 = polygon area * [4*tan(180/n)] / n
where n is the number of sides
side length^2 = 55 sq inches * (4*tan(180/6)) / 6
side length^2 = 55 sq inches * 4 * tan (30) / 6
side length^2 = (55 sq inches * 4 * 0.57735) / 6
side length^2 =

Answer:
x + 2y
Step-by-step explanation:
so 3x + 2y - 3x, group the like terms 3x - 3x = x
So x + 2y, i think i did that right
