Formula: A = ½absin(C)

works when you have two angles and one side length

Formula: c² = a² + b² - 2abcos(C) or cos(C) = (a² + b² - c²)/2ab

you would use this in order to find the 3rd side length of a triangle then you would use the area of a triangle formula in order to to find the area.

In order to find an angle between two lines, you would first need to know the slopes of both lines so m1 and m2. Then you would use the Tangent function formula of: tan(theta) = (m2 - m1)/(1+ m1m2). For that solution, you would then make it theta = tan^-1 ((m2 - m1)/(1+ m1m2).)

formula: n = any integer and to find a consecutive integer you would do n + 1, so n, n + 1, n + 2

2n

(2n + 1)

2n, (2n + 2), (2n + 4)

(2n + 1) (2n + 3) (2n + 5)

Prove that the product between an odd and an even integer are always even:

2n(2n + 1) = 4n² + 2n →2(2n² + 1) Since any even integer is a multiple of two, it must be even.
