Vertically Opposite Angles with a Variable (āĻāϞāĻāϏāĻš āĻŦāĻŋāĻĒā§°ā§āϤ āĻļā§ā§°ā§āώ āĻā§āĻŖ)
Definition: Vertically Opposite Angles are the pairs of angles formed when two lines intersect. These opposite angles are always equal. If the angles contain a variable (such as x), set the opposite angles equal to each other and solve for the variable. āϏāĻāĻā§āĻāĻž: āĻŦāĻŋāĻĒā§°ā§āϤ āĻļā§ā§°ā§āώ āĻā§āĻŖ āĻšā§āĻā§ āĻĻā§āĻāĻž ā§°ā§āĻāĻžāĻ āĻĒā§°āϏā§āĻĒā§°āĻ āĻā§āĻĻ āĻā§°āĻŋāϞ⧠āϏā§āώā§āĻāĻŋ āĻšā§ā§ąāĻž āĻŦāĻŋāĻĒā§°ā§āϤ āĻĻāĻŋāĻļā§° āĻā§āĻŖāϝā§ā§°āĨ¤ āĻāĻ āĻā§āĻŖ āĻĻā§āĻāĻž āϏāĻĻāĻžāϝāĻŧ āϏāĻŽāĻžāύ āĻšāϝāĻŧāĨ¤ āϝāĻĻāĻŋ āĻā§āĻŖāϤ āĻāϞāĻ (āϝā§āύ⧠x) āĻĨāĻžāĻā§, āϤā§āύā§āϤ⧠āĻŦāĻŋāĻĒā§°ā§āϤ āĻļā§ā§°ā§āώ āĻā§āĻŖ āĻĻā§āĻāĻž āϏāĻŽāĻžāύ āϧ⧰āĻŋ āϏāĻŽā§āĻā§°āĻŖ āĻāĻ āύ āĻā§°āĻŋ x-ā§° āĻŽāĻžāύ āĻāϞāĻŋāϝāĻŧāĻžāĻŦ āϞāĻžāĻā§āĨ¤
Example / āĻāĻĻāĻžāĻšā§°āĻŖ: If one angle is (3x + 10)° and its vertically opposite angle is (5x − 6)°, then
3x + 10 = 5x − 6
2x = 16
Note: Vertically opposite angles are always equal. (āĻŦāĻŋāĻĒā§°ā§āϤ āĻļā§ā§°ā§āώ āĻā§āĻŖ āϏāĻĻāĻžāϝāĻŧ āϏāĻŽāĻžāύ āĻšāϝāĻŧāĨ¤)
