Answer: x= .
.
Step-by-step explanation: We are given a segment parallel to the base.
Therefore, sides of big triangle and small triangles would be in proportion.

Setting values for the shown triangle, we get


On cross multiplication, we get
16(2x+7) = 38(x)
32x + 112 = 38x.
Subtracting 112 from both sides, we get
32x + 112-112 = 38x -112
32x = 38x-112
Subtracting 38x from both sides, we get
32x-38x = 38x-38x-112
-6x = -112
Dividing both sides by -6, we get

x= .
.
<h3>Therefore, x= .

Answer:
A coordinate system,or Coordinate plain ,is used to locate points in a 2-dimensional plane.
explanation:
A coordinate plain is formed by the intersection of two lines.One line is vertical and the other is horizontal.The vertical line is called y- axis and the horizontal line is called x-axis. It is two dimensional plane,which means it has length and breadth but no depth.The point where both the lines intersect is called the point of origin.Any point can be located on the coordinate plain by numbers(x,y). These pair of numbers are called coordinates.
It is used to plot points and lines.This system explains algebraic concepts .it has four equal divisions called quadrants namely I ,II,III,IV.
well first off do you understand what it means when it says the "square root of x"?
