WebFind the measure of the missing angles x and y in the diagram below. Solution x = 80 o (the exterior angle = the opposite interior angle). y + 70 o = 180 o (opposite angles are supplementary). Subtract 70 o on both sides. y = 110 o Therefore, the measure of angles x and y are 80 o and 110 o, respectively. Example 2 WebOct 12, 2024 · To find the missing angle in a triangle use the following steps: Add the two known angles together. Subtract this result from 180° The two known angles are 94° and 40°. The first step is to add 94° and 40°. 94° + 40° = 134°. The next step is to subtract 134° from 180°. 180° – 134° = 46°. The missing angle is 46°.

WebMar 3, 2024 · For example, if you know that 4 of the angles in a pentagon measure 80, 100, 120, and 140 degrees, add the numbers together to get a sum of 440. Then, subtract this sum from the total angle measure for a pentagon, which is 540 degrees: 540 – 440 = 100 degrees. So, the missing angle is 100 degrees.
