The angle congruent to ∠6 are ∠8, ∠3, ∠9 and ∠14
<h3>How to find congruent angles?</h3>
When parallel lines are cut by a transversal, angle relationships are formed. They include corresponding , alternate and many more.
L║m
n ║ q
Therefore, the angles congruent to ∠6 by alternate or corresponding relationship are as follows:
∠6≅∠8≅∠3≅∠9≅∠14

Answer:
(n-2)180 (this is the equation to find the sum of interior angles)
(4-2) 180 (plug in the amount of angles in the polygon and then solve)
2* 180
360
360 - 115 -100- 73= 72 (360 is the sum of all angles for this polygon. so subtract the known angles to find the unknown one)
measure of angle B is 72 degrees

Hallo ^_^
Quadratic Equation :
ax² + bx + c = 0
From the task :
x² + 1/20 x = 1/20
Switch sides :
x² + 1/20x - 1/20 = 0
Multiple each sides by 2020(x² + 1/20x - 1/20) = 0(20)
⇒ 20x² + x - 1 = 0
From that :
a = 20, b = 1 and c = - 1
Solve x using quadratic formula :
Substitution using the formula :
