Using Pythagoras theorem

<u>Question 1</u>
Now, cosecant = 1/sin
Therefore:

<u>Question 2</u>
Now, secant = 1/cos
Therefore:

To answer the question above, simplify both sides of the equation. This gives,
8x - 3 = 8x + 14
Next, cancel the term 8x because it appears on both sides of the equation giving,
-3 = 14
That is NOT true. Therefore, the answer is the equation is NEVER TRUE.
3x+22.5 = 69.75
-22.5 -22.5
3x = 47.25
/3 /3
x = 15.75
