It measures 104 degrees
Supplementary is what makes 180 degrees. 180-76=104
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95
middle angle= 51 degrees smallest angle= 25 degrees largest angle= 104 degrees x=25 ; y=104 I can't really show you how I got the answer but I suggest you draw a picture and then it's much easier to figure out. We don't need a figure to compute the measure of the angles, since we know that the sum of the measure of angles in a triangle is 180 degrees. Let x be the smallest angle, so the middle angle is 1 + 2x, and the larger angle is 53 + 1 + 2x or 54 + 2x. Then we have: x + (1 + 2x) + (54 + 2x) = 180 5x + 55 = 180 5x + 55 - 55 = 180 - 55 5x = 125 5x ÷ 5 = 125 ÷ 5 x = 25 1 + 2x = 1 + 2(25) = 51 54 + 2x = 54 + 2(25) = 104
8x = -104 Therefore, x = -104/8 x = -13

104 degrees: 180 - (2 x 38)

(360 - 104)/2 = 128 degrees.
Complementary angles are acute angles. An angle that measures 104 degrees is an obtuse angle and therefore cannot have a complement.

An angle that is 104 degrees would be considered an "Obtuse" angle. This is because the degrees in the angle are over 90.
An angle of 104 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees
