The sum of the angles of any triangle must be 180 degrees. Call the measure of smallest angle in this instance s. From the problem statement, s must be the smallest angle, because both the other two are defined in a manner that makes each of them larger than the first. Therefore, 3s + (s + 40) + s = 180, or 5s = 180 - 40 = 140, or s = 28.
The third angle is (128 degrees) minus (the second angle).
It is 90-28 = 62 degrees
It will be 62 degrees because 90-28 = 62
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
54 degrees
100.
If its a right angle triangle then the second acute angle is 62 degrees
The third angle is (128 degrees) minus (the second angle).
It is 90-28 = 62 degrees
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.
It will be 62 degrees because 90-28 = 62
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 angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 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.
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
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.
