The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
90 degrees
90 degrees
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95
The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
100.
If that's a triangle, the third angle is 90 degrees.
It is an obtuse triangle and the third angle would measure 35 degrees
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
