If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation.
Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees
The 3rd angle is 80 degrees
Absolutely not!If C is the right angle, then by conventional notation, c is the hypotenuse and so is the longest side!
Its 3rd angle is 180-125 = 55 degrees
It is 800!
The isosceles triangle will have a top angle of 66 degrees and two equal base angles of 57 degrees which all add up to 180 degrees.
96˚all angles to a triangle equals 180˚
The sum of all angles in any triangle equals 180 degrees.
all triangles equal 180 degrees so 180/3 equals 60 so, the measure of each angle of an equilateral triangle is 60 degrees.
Anglw C is 63 degrees because the 3 interior angles of a triangle add up to 180 degrees
45 degrees
67 degrees
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
Angle C = 50 degrees. ------------------------------- A triangle equals 180 degrees. 60.5 + 69.5 = 150 180-150 = 50.
82 degrees (180 degrees in a triangle)
The sum of a triangle equals 180 degrees
55 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
