What is 56+24?

The question is in the picture. Thank you!

(Fermat’s little theorem)
(1) Show that 17 | 2^56 + 3^56^.
(2) What is the remainder of 5×14^23 ÷ 115?

1. find the angle ? that makes the statementtrue: cos (3? - 59 degrees) = sin(? + 13 degrees)

Choose best answer below:

102 degrees

-34 degrees

31 degrees

34 degrees

90 degrees

56 degrees

12 degrees

59 degrees

2. Factor the trigonmetric expression: (cot x -tan x)^2 - (cot x + tan x)^2 = ?

3. find the remaining trigfunctions:

sin ? = ?

cos ? = ?

tan ? = 7/24

csc ? = ?

sec ?= ?

cot ? =24/7
