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.
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
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
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.
The triangle is an isosceles triangle.
100.
The third angle is (128 degrees) minus (the second angle).
