In summary, The formula for finding m<2 when m<1 and m<2 are given is m<2 = 180 - m<1, where m<1 and m<2 are angles in degrees. The angle labeled as m<1 is always the smaller angle, and the angle labeled as m<2 is always the larger angle. You can use the formula as long as you know which angle is smaller and which angle is larger. You only need the two angles to find m<2 using the formula. This formula is specifically for finding the third angle in a triangle when two angles are given and will not work for other types of shapes.

<1 and <2 are vertical angles. If m<1 = 17x + 1 and m<2 = 20x - 14, find m<2.

As vertical angles have the same measure, set 17x + 1 = 20x - 14, solve for x and substitute that value for x into the expression for angle 2 (or angle 1 if you prefer; they both have the same measure). The result is the desired measure.
 

FAQ: Finding m<2 When m<1 & m<2 are Given

What is the formula for finding m<2 when m<1 and m<2 are given?

The formula for finding m<2 when m<1 and m<2 are given is m<2 = 180 - m<1, where m<1 and m<2 are angles in degrees.

How do I know which angle is m<1 and which angle is m<2?

The angle labeled as m<1 is always the smaller angle, and the angle labeled as m<2 is always the larger angle.

What if the given angles are not labeled as m<1 and m<2? Can I still use the formula?

Yes, you can still use the formula as long as you know which angle is smaller and which angle is larger.

Do I need any other information besides the two angles to find m<2?

No, you only need the two angles to find m<2 using the formula.

Can I use this formula for any triangle?

No, this formula is specifically for finding the third angle in a triangle when two angles are given. It will not work for other types of shapes.
