Answer:
tan 15 + cot 15
= sin 15 / cos 15 + cos 15 / sin 15
= (sin²15 + cos²15) / (sin 15 cos 15)
= 1 / (1/2 sin 30)
= 2 / sin 30
= 2 / (1/2)
= 4
Step-by-step explanation:
Decimal Form: 11.5
Fraction Form: 11 1/2
3).
4).
If it was by 10, k = 3 by 10
k = 30
5).
Solution:
<u>Note that:</u>
<u>Use the formula to convert the line in point slope form.</u>
The equation of the line (In point slope form) is y - 1 = 4(x - 1).
Below.
So let's do this Divide both sides.
equals to,
y+2>2
Cancel out equal terms.
y>0.
