It is a scalene triangle and the 3rd angle is 47 degrees
71 degrees
109Supplementary angles add to 180 degrees. 180 - 71 = 109.
Complementary angle is 71 degrees and supplementary angle is 161 degrees
90 - 19 = 71 degrees.
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.
It is an acute angled scalene triangle.
It is a scalene triangle and the 3rd angle is 47 degrees
71 degrees
The sum of the interior angles of a triangle add up to 180o. So 180 - (45 + 71) = 64o
If the first two angles of a triangle are 45 degrees and 71 degrees then the 3rd angle is 64 degrees.
i think it is 71 . i think because you can add 62+47 =109-180 so put it like this 108 -109=71
They are its exterior angles and the 3 exterior angles of a triangle add up to 360 degrees whereas its 3 interior angles add up to 180 degrees.
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.Use the fact that the sum of the angles, in a triangle, adds up to 180 degrees.
77. The sum of the three angles in a triangle equal the sum of 180 degrees
Since it is an Isosceles Triangle and T = 38 Then subtract 38 from 180 , which 142 . 142 is the total of the two equal angles R & S . So divide 142 by 2 = 71 So angles R(y) & S (y) are both 71 degrees. Remember with an Isosceles Triangle, not only are two sides of equal length , but two angles are of equal size.
