Help I am very bad at math I need answers by tomorrow if you can help please do​

Step-by-step explanation:

(a - b)(a +b) = a² - b²

1 - Sin² A = Cos² A

2)  Sec² A - Tan² A = 1

3) LHS  = Cosec² A + Cot² A

             = Cosec² A +  Cosec² A - 1

            = 2Cosec² A - 1   = RHS

idk

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
