Answer:
x=-18
Step-by-step explanation:
What you have do do is look at the word <em>difference. </em>
Difference means subtraction so you will subtract x and -37.
x-(-37)=19. You will then make the negative a positive and subtract 37 from both sides.
x=-18 is your answer.
Answer:

Step-by-step explanation:
Answer:
1.
Step-by-step explanation:
sec 16° cosec 74° - cot 74° tan 16°
= 1/ cos 16 * 1/ sin 74 - 1/tan 74 * tan16
= 1/ cos16 sin 74 - cos74/ sin74 * sin 16 / cos 16
Now cos 16 = sin 74 and sin 16 = cos 74 (supplementary angles) so:
= 1 / cos^2 16 - sin 16/cos 16 * sin 16 / cos 16
=( 1 - sin ^2 16 )/ cos^2 16
= cos^2 16 / cos^2 16
= 1.
