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.

What is the measure of the third angle of a triangle if one angle measures 52 degrees?
The third angle is (128 degrees) minus (the second angle).
What will be the measure of the second acute angle of a right triangle if the first acute angle measures 28 degrees?
It is 90-28 = 62 degrees
What would be the measure of the second acute angle of a right triangle if the first acute angle measure is 28?
It will be 62 degrees because 90-28 = 62

What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 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 measure of the second angle in a triangle is five less than the first. The third angle is thirteen more than twice the first. Find the measure of each angle?
The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees
The measure of the second angle of a triangle is 21 degrees more then the measure of the first angle the measure of the third angle is 15 degrees less than the measure of the first angle. each is?
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.
What is the triangle that has one angle is 40 degrees and a second angle is 50 degrees?
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
The second angle in a triangle is one third as large as the first the third angle is two thirds as large as the first angle find the angle measures?
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.
