However, since a triangle cannot have two obtuse interior angles, the two missing angles must be the ones that are congruent. Since the total angle measure of a. Here’s how to find the measure of an angle for a triangle. All three angles add to 180 degrees, so simply subtract the known angles from. If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in. Find The Measure Of An Angle : Example Question #1. What is the sum of the interior angles of a triangle? Possible Answers:.I have to find angle A’s measure. Since the interior angles of a triangle add up to be 180 degrees, I set up the equation like so: x + 59 + x.

## how to find the measure of a missing angle

Just like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. Sometimes we can. First, know that all the angles in a triangle add up to 180 degrees. Find the degree measure of the missing angle. Possible Answers:.Since the two angles are supplementary, their sum is 180°. To find the missing angle, subtract the given angle from 180°. The result is the missing angle. . To calculate a missing angle, you add the other two angles, and then subtract that sum from 180. For example, if you have two angles, 72 degrees and 28. Find the measures of the missing angle in the following triangles. · 32o · 45o · 60o · 90o · Given ?ABC, ?A=120? ?B=28? Sum of angles of the triangle, ?A+?B+.
