two-thirds of an angle is 30degree more than its supplemant. find the angle

They are both acute angles because they are less than 90 degrees and the 3rd angle is 71 degrees which is also an acute. The triangle is a scalene triangle.

Remember the sum of the 3 angles of a triangle = 180degrees Let angle 1 = x angle 2 = 2x angle 3 = x-20 Sum = x + 2x + x - 20 =180o 4x - 20 = 180o 4x = 200o x = 50o 2x = 100 o x - 20 = 30o angle 1 = 50o angle 2 = 100 o angle 3 = 30o

more than a 90 degree angle but less than a 180 degree angle

In degrees, its measure is 180 less the sum of the two angles at the base of the triangle.

An obtuse triangle

It is an acute angle which is greater than 0 but less than 90 degrees

The angles are: 43 degrees. 38 degrees and 99 degrees which all add up to 180 degrees

40 degres

That depends on what type of triangle it is but in general:- 180-interior angle = exterior angle

Yes. A triangle can be classified as: For angles 1. If a triangle has at least 1 angle that has an angle measure of more than 90 degrees, it can be called an obtuse triangle 2. If a triangle has 3 angles that are less than 90 degrees, it's a acute triangle. 3. If a triangle has an angle that has an angle measure of 90 degrees, it can be called and right triangle For sides: 1. All equal sides= equilateral. 2. 2 equal sides= Isosceles 3. No equal sides= scalene

Yes. In fact, it must contain TWO angles of measure less than 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.
