Solution we have been given that lines l and m are parallel.

How to find missing vertical angles. If two angles are complementary, that means that they add up to 90 degrees. Finding missing angles how do you use complementary angles to find a missing angle? What is the missing angle?

Subtract the two known angles from 180° 180 °: Here, d = 36 o and a, b and c are unknown. Find angles a°, b° and c° below:

Trying to find a missing interior angle measurement in a triangle? Therefore, x + 65° = 180° ⇒ x = 180° 65° = 115° step 2: Find ac in the following triangle.

1.if you know at 2 angles of a triangle, add those 2 angles and subtract from 180. We need to find the remaining angles. Find the given angles step 2:

The triangle sum theorem might help. If you are, that knowledge. What is the missing angles in the given triangle?

Another term for being equal is congruent. By the rule of vertical angles, b = d = 36 o then, a = c =? Angles a° and c° are also vertical.
