Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α
Step-by-step explanation:
12x > 18x - 27 - 15
12x > 18x - 42
12x - 18x > -42
-6x > -42
x < -42/-6
two negatives make a positive so now its x < 42/6
Lastly divide 42/6 so it can equal 7
Answer: X < 7.
A midsegment is given by the formula:

Where x1, x2, y1, and y2 correspond to their respective coordinates. We can do the equation:

This gets us a midpoint coordinate of <span>
(1,1)</span>As for distance, it will be found by doing:

We can do the following:



This simplifies to

:)
Answer: 4x - 6 = 563
Suma 6 a ambos lados para aislar la variante 4x.
4x - 6 = 563
+6. +6
4x = 569
Divide ambos lados por 4
4x/4 = 569/4
X = 142.5
