Midsegment of triangle <br> Find X
Charra [1.4K]

Answer:

10 = x

Step-by-step explanation:

This is what is called the Midsegment Theorem, which states that the relation of a triangle's midpunkt is parallel to the triangle's third side, and the mid-segment length is half the third side length, so you would take half of 4x + 20 and set that expression equal to the midsegment:

2x + 10 = 3x

-2x - 2x

____________

10 = x

You then plug this back into both expressions above to get the double-segment of 60 and the mid-segment of 30. We can tell this is correct because 30 and 60 are relatively proportional to each other.

I am joyous to assist you anytime.

Can you guys do this ASAP, thanks will mark brainliest
dybincka [34]

Answer:

A) Graph an quadratic equation for a parabola (x being to the power of 2), and a linear equation. Examples would be y=x² and y=x.

B) Parabolas that share the same vertex can simply have another transformation done to them. For example: y= 5x² and y=3x².

C) A line that would pass through these would be any linear graph WITHOUT a 'b' value, so a y intercept of 0. An example would be y=5x.
