You are looking at right angles in the problem. Right angles are 90 degrees.
So set up the problem to solve for X using:
90=4x+12
90-12=4x
78=4x
39/2 or 19.5 = x
A geometric plane is two-dimensional. Standing at one point in the plane and picking two directions to travel which are not opposites of one another, any direction of travel on the plane can be obtained by composing these two directions. Since it is two directions, the plane is two-dimensional
Answer:
84 units
Explanation:
If B is the midpoint of line AC, then B divides AC into two equal parts (AB and BC).
Therefore:
AB=BC
2x-8=x+17
2x-x=17+8
x=25
Therefore, the measure of the line segment AC
=2(2x-8)
=2(2(25)-8)
=2(50-8)
=2(42)
AC=84 units
Try this : <span>3x10^6 + 2x10^4 + 9x10^3 + 2x10^2 + 5x10 + 1</span>
(x^2+5x-36)/(x^2-16)
=(x^2+9x-4x-36)/(x^2-4^2)
=x(x+9)-4(x+9)/(x+4)(x-4)
=(x-4)(x+9)/(x+4)(x-4)
=x+9/x+4
Hope this helps.
