If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 degrees.
70 degrees
85 the three angles of a triangle should add up to 180 degrees
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
That's an isosceles triangle.
Well, honey, the sum of all angles in a triangle is 180 degrees. So if two angles are already 54 degrees each, the third angle would be 72 degrees to make up the total. It's basic math, darling.
In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.
This is a scalene triangle: The sum of the angles of any triangle must be 180 degrees. Subtracting the given angles from 180 leaves 98 degrees for the third angle. Therefore, no two angles of the triangle are equal, and no two sides can be equal.
70 degrees
85 the three angles of a triangle should add up to 180 degrees
no. the angles in a triangle must add up to 180 degrees. The right triangles must have an right angle (90 degrees). If you add up all the angles they will not measure 180 degrees.
Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.
