It is: 180-149 = 31 degees
A scalene triangle and the other angle is 47 degrees
The premise is impossible. The sum of the angles of a triangle is 180 degrees.
The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
All triangles have 3 interior angles that add up to 180 degrees and they are:- Right angle triangle: 90 degree angle and 2 acute angles Obtuse triangle: An obtuse angle and 2 acute angles Scalene triangle: 3 acute angles of different sizes Isosceles triangle: 2 equal angles and another angle Equilateral triangle: 3 equal angles that each measures 60 degrees
The 3 interior angles in any triangle add up to 180 degrees.
The triangle has three exterior angles. Added together, their total is 180 degrees.(Same as the total of the three interior angles when they're added together.)
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
yes, just add all the angles together and if it equals 180 your ok
If the triangle has a right angle in it then it's a right triangle.A right angle triangle has 3 sides and 3 interior angles of 90 degrees and two acute angles which all together add up to 180 degrees.
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
An obtuse triangle is one which has one angle that is greater than 90 degrees.
In a triangle, if an angle is adjacent (shares a side) and supplementary (adds up to 180 degrees) to one of the interior angles, it means that the two angles together form a straight line. In other words, the three angles of the triangle add up to 180 degrees.
All triangles have a total of 180 degrees.The internal angles of any triangle add up to 180 degrees.Therefore, a RIGHT triangle's angle's added together equal 180 degrees.The Right Angle = 90 degrees + the other 2 angles total 90 degrees, making the total number of degrees in a Right Angle Triangle = 180 degrees.
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees
A right angle triangle has only 1 right angle of 90 degrees and two acute angles that add up to 90 degrees whereas the 3 angles add up to 180 degrees
The third angle has to be 90 degrees so it would be a right angle triangle.
