a triangle has 180 degrees 35+85=120 180-120=60 the third side is 60 degrees
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
Two supplementary angles add up to 180 degrees. If one of the angles is x degrees, then the other angle will be 3x - 60. So we have: x + 3x - 60 = 180 4x - 60 + 60 = 180 + 60 4x = 240 4x/4 = 240/4 x = 60 3x - 60 = 3(60) - 60 = 120 Thus, the angles have measures of 60 and 120 degrees.
S + M + L = 180 S = L - 90, M = L - 60 so (L - 90) + (L - 60) + L = 180 ie 3L = 180 + 90 + 60 L = 60 + 30 + 20 , = 110 degrees, so M = 50 degrees and S = 20 degrees
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
90
Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.
<p><p> 180-x=3(90-x)-60 180-x=270-3x-60 3x-x=270-180-60 2x=30 x=15
To get radian measure of angle given in degrees, multiple the measure in degrees by PI/180. Example: 60 deg = 60 * PI/180 rad = 1.047 rad.
A right angle is 90 degrees
if you know the measure of the angle then all you do is subtract that measure from 180 or 360 or 540, it depends on what your shape is. (e.g. you have a triangle (180) and you're trying to find the supplement of the angle 60 then you do, 180-60=120) :) hope that helps!
all triangles equal 180 degrees so 180/3 equals 60 so, the measure of each angle of an equilateral triangle is 60 degrees.
no. the angles in a triangle must add up to 180 degrees. The right triangles must have an right angle (90 degrees). If you add up all the angles they will not measure 180 degrees.

The adjacent angles of a parallelogram are supplementary. This means that angle A + angle B = 180 deg.Since angle B = 2*angle A, then angle A + 2*angle A = 180 deg ie 3*angle A = 180 deg so that angle A = 60 deg.
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
All angles in a triangle must equal 180, therefore 180 - 120 = 60
