Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
Answer:
18
Step-by-step explanation:
The equation can be resolve to two equations:
... 34-x = 25 . . . . . solution x = 34 - 25 = 9
... 34-x = -25 . . . . solution x = 34 - (-25) = 59
Your solution is 9, 59.
Angle 1 = 128
Angle 2 = 64
Angle 3 = 64

Hope this helps!! :)
Here is a trick I always use:
Get rid of both zeros in100 for now
So just do 697*1 which is just 697
Now add the two zeros to your answer to get 69,700 which is the final answer
