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.
Answer:
Equation is 42t
So,
t=12
According to equation
Put value of t
=42(12)
=504
So 2nd option is correct.
Answer:
y < - 6
Step-by-step explanation:
Given
- 2y > 12
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
y < - 6
