Finding the Other Angles of a Triangle

To find the other angles of a triangle when one angle is given as 100 degrees, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

Let's consider a few cases:

Case 1: If one angle of a triangle is 100 degrees, we can find the other two angles by subtracting 100 from 180 and dividing the result by 2. This is because the sum of the other two angles must be equal to the remaining angle needed to make the total sum of 180 degrees.

Using this formula, we can calculate the other two angles as follows:

Angle 1 = (180 - 100) / 2 = 40 degrees Angle 2 = (180 - 100) / 2 = 40 degrees

Therefore, in this case, the other two angles of the triangle are both 40 degrees.

Case 2: In another case, let's assume that one angle of a triangle is 100 degrees, and we are given the measure of another angle.

For example, if we know that one angle is 100 degrees and another angle is 30 degrees, we can find the third angle by subtracting the sum of the two known angles from 180 degrees.

Using this formula, we can calculate the third angle as follows:

Angle 3 = 180 - (100 + 30) = 50 degrees

Therefore, in this case, the third angle of the triangle is 50 degrees.

It's important to note that the sum of the three angles in any triangle is always 180 degrees. So, if you know the measure of one angle and the measure of another angle, you can always find the measure of the third angle by subtracting the sum of the known angles from 180 degrees.
