All angles in a triangle must equal 180, therefore 180 - 120 = 60
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
77. The sum of the three angles in a triangle equal the sum of 180 degrees
55°
The missing angle measure is 100 degrees.
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
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
...a right triangle.
77. The sum of the three angles in a triangle equal the sum of 180 degrees
Always remember that the sum of all the angles in a triangle is always equal to 1800,therefore the third angle is equal to 1800 - (350 + 750 ) = 700
If two angles of a triangle each measure 55 what is the measure of the third angle?
Two angles of a triangle add up to 65°. What is the measure of the third angle?
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
55°
If you mean the equal angles were each 70o then 180 - 140 ie 40o
The missing angle measure is 100 degrees.
100.
The triangle is an isosceles triangle.
