The third angle of what shape?
The third angle is (128 degrees) minus (the second angle).
Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
Assuming you mean the third angle of a triangle... 64 degrees.
Angle 1 = 30 degrees Angle 2 = 50 degrees Angle 3 = 100 degrees.
The third angle is (128 degrees) minus (the second angle).
Let's assume the measure of the first angle is x degrees. The second angle is one-third as large as the first, so its measure is (1/3) * x = x/3 degrees. The third angle is two-thirds as large as the first, so its measure is (2/3) * x = 2x/3 degrees. Therefore, the measures of the angles in the triangle are x degrees, x/3 degrees, and 2x/3 degrees.
100.
If the first two add up to 45 degrees, then the third angle is 135 degrees.If each of the first two is 45 degrees, then the third angle is 90 degrees.
Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.
Let the second angle be x degrees. The first angle would then be x + 24 degrees, and the third angle would be 4x degrees. According to the triangle angle sum theorem, the sum of all three angles in a triangle is 180 degrees. Therefore, you can set up the equation x + (x + 24) + 4x = 180 and solve for x to find the measures of all three angles.

The angles are 40, 80 and 60 degrees.
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
Let the first angle be x the second angle be 4x and the third angle be 80+4x+x: x+4x+80+4x+x = 180 Collect like terms: 10x = 180-80 10x = 100 x = 10 Therefore the measure of the second angle is 40 degrees.
If the first two angles of a triangle are 45 degrees and 71 degrees then the 3rd angle is 64 degrees.
