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.
The measures of two angles of a triangle are given find the measure of the third angle 47 and 62
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
i think it is 71 . i think because you can add 62+47 =109-180 so put it like this 108 -109=71
If the first two angles of a triangle are 45 degrees and 71 degrees then the 3rd angle is 64 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.
The Exterior angles are named as 'REFLEX' angles. At any one angular point, the sum of the Interior angle and the Exterior angle equals 360 degrees. There being three angles in a triangle, then the sum of all the angles is 3 x 360 = 1080 degrees. Since the sum of the three interior angles is 180 degrees., then the sum of the exterior (reflex) angles is 1080 - 180 = 900 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.
