Absolutely not!If C is the right angle, then by conventional notation, c is the hypotenuse and so is the longest side!
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
28 The Law of Sines: a/sin A = b/sin B = c/sin C 24/sin 42˚ = c/sin (180˚ - 42˚ - 87˚) since there are 180˚ in a triangle. 24/sin 42˚ = c/sin 51˚ c = 24(sin 51˚)/sin 42˚ ≈ 28
The area is 99.0 square units.
180 degrees C = 356 degrees F.
30 degrees explanation 2Cosx-radical 3=0 Then 2cosx=radical 3 and cos x=(radical 3)/2 Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle. So the answer is 30 degrees.
61 degrees (180 degrees in a triangle)
A triangle equals to 180 degrees
The sum of a triangle equals 180 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.
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
Yes the 3 interior angles of any triangle always add up to 180 degrees.
