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
In an isosceles triangle, two angles are equal. Since the angles provided are 54 degrees and 63 degrees, the equal angles must be 54 degrees. The sum of the angles in any triangle is 180 degrees. Thus, the measure of the third angle is calculated as follows: 180 - 54 - 54 = 72 degrees.
Absolutely not!If C is the right angle, then by conventional notation, c is the hypotenuse and so is the longest side!
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.
It is 800!
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.
If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 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.
