Pls help no need for long explanations just a summary ​
mr Goodwill [35]

Answer:

<em>FG - it is midline. FG = 5.</em>

Explanation:

<em>A midline in a triangle is a line segment connecting the midpoints of two sides.</em>

<em>A midline is half the length of the side to which it is parallel.</em>

<em />\dfrac{CE}{FG} =2\\\\ \dfrac{9x-26}{7x-23} =2\\\\9x-26=2(7x-23)\\9x-26=14x-46\\14x-9x=46-26\\5x=20\\x=4<em />

<em>CE = 9 · 4 - 26 = 10</em>

<em>FG = 10/2 = 5</em>

If the gradient of a line, A, is 4, what is the gradient of a line which is perpendicular to A?
Ne4ueva [31]

Answer:

m = - 1/4

Step-by-step explanation:

When two line is perpendicular to each other the product of them is - 1

So let the other line be B

Gradient of B = t

Gradient of A = 4

t \times 4 =  - 1 \\  t =  - \frac{1}{4}

therefore m = - 1/4
