supplementary
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
Each exterior angle: 90 13' 50.77'' Each interior angle: 1700 46' 9.23''
180 - 46 = 134 degrees.

Supplementary angles add up to 180 degrees
It is an angle whose measure is 46/360 = 23/180 of a full rotation.

77 degrees
An angle of 46 degrees is an acute angle because it is greater than 0 but less than 90 degrees.
257 - 134 - 46 = 77
Third angle would be 46 degree. 180-44-90 =46
180 - 46 = 134
So ? ^_^ You must want to find the third angle. It's 180º minus the two you already have. So it's 62º.
180 - (46 + 108) = 26 degrees180 - (46 + 108) = 26 degrees180 - (46 + 108) = 26 degrees180 - (46 + 108) = 26 degrees
