Solving Equations With Vertical Angles Youtube Practice solving equations by setting expressions equal to each other. the expressions represent the measure of vertical angles. this video reviews how to. To find an unknown angle measure, sometimes it is helpful to write and solve an equation that represents the situation. for example, suppose we want to know the value of \ (x\) in this diagram. figure \ (\pageindex {12}\) using what we know about vertical angles, we can write the equation \ (3x 90=144\) to represent this situation. Step 1: set the expressions labeling the angles equal to each other. we need to create an equation using the labels as each side of the equation. 3 x 25 = 6 x − 5. step 2: isolate the variable. Example: given the diagram below, determine the values of the angles x, y and z. solution: step 1: x is a supplement of 65°. therefore, x 65° = 180° ⇒ x = 180° 65° = 115°. step 2: z and 115° are vertical angles. therefore, z = 115°. step 3: y and 65° are vertical angles. therefore, y = 65°.

Example: given the diagram below, determine the values of the angles x, y and z. solution: step 1: x is a supplement of 65°. therefore, x 65° = 180° ⇒ x = 180° 65° = 115°. step 2: z and 115° are vertical angles. therefore, z = 115°. step 3: y and 65° are vertical angles. therefore, y = 65°. Example 1: two angles that are vertically opposite. find the value of angle x.x. identify which angles are vertically opposite to one another. the angle labeled xx and the angle with value 117 ∘ 117∘ are vertical angles, since their vertex is created by two straight lines intersecting. So imagine two lines crossing, just like this. and they could literally be lines, and they're intersecting at a point. this is forming four angles, or you could imagine it's forming two sets of vertical angles. so if this is the angle that you care about, it's a vertical angle, it's the one on the opposite side of the intersection.
