You need to know the area and height to solve this equation. For a triangle with sides a b and c if a and b are known and C is the included angle the angle between the sides C can be worked out with the cosine rule. Acute angled TriangleIn this triangle all three angles should be less than 90-degrees.
The formula is.
Specific heat capacity is the amount of heat required to heat 1 g of a substance through 1 degree of temperature. For a triangle with sides a b and c if a and b are known and C is the included angle the angle between the sides C can be worked out with the cosine rule. S is called the semi perimeter meaning half the perimeter Area of the triangle. Acute angled TriangleIn this triangle all three angles should be less than 90-degrees.
