Answer:
<em>x = 49°</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
The sum of the internal angles in any triangle adds up to 180°.
The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.
The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:
43° + 39° + 2x = 180°
Operating:
82° + 2x = 180°
Subtracting 82°:
2x = 180° - 82° = 98°
x = 98°/2 = 49°
x = 49°
Plug the two points into the slope formula.
m = y2-y1/x2-x1
m = (-4 - 5)/(0 - 2)
m = -9/-2
m = 4.5
So the slope is 4.5
2x - 6 = 20
2x = 20 + 6
2x = 26
x = 26/2
x = 13 <==
