The two angles are supplements, because the measures of supplementary angles add up to 180 degrees. 46 + 134 = 180.

For an isosceles triangle with vertex 46 degrees, the sum of the remaining two base angles is 180-46 = 134 degrees. Base angles are equal because it's isosceles, so each angle is half of their sum. 134/2 = 67 degrees. Thus, any isosceles trapezoid formed inside that isosceles triangle by drawing parallel lines to the triangle's base, will have base angle measures of 67 degrees, which are triangle's base angles.
77 degrees
257 - 134 - 46 = 77
46 x 90 degrees = 4140o

No but they are supplementary angles because they add up to 180 degrees
180 - 46 = 134 degrees.

To find the number that, when added to 46, equals 180, you would subtract 46 from 180. So, 180 - 46 = 134. Therefore, the number that, when added to 46, equals 180 is 134.
46 x 90 degrees = 4140o
So ? ^_^ You must want to find the third angle. It's 180º minus the two you already have. So it's 62º.
This is a scalene triangle: The sum of the angles of any triangle must be 180 degrees. Subtracting the given angles from 180 leaves 98 degrees for the third angle. Therefore, no two angles of the triangle are equal, and no two sides can be equal.
180 - 46 = 134
