The answer is 15 trust me.
Hi, We know:
Sin(a + b) = 2.Sin(a).Sin(b)
Then,
= 2Sin(a).Cos(b)/Cos(a).Cos(b)
Canceling Cos(b)
= 2Sin(a)/Cos(a)
As Tan(a) = Sin(a)/Cos(a)
Then we will stay:
= 2Tan(a)
Or
= Tan(a) + Tan(a)
There is anything wrong on the alternatives
Answer:
True
Step-by-step explanation:
Answer:
1950
Step-by-step explanation:
If you were 24 in 1974, simply subtract 24 from 1974 to find what year you were born in:
1974-24= 1950
Of course, it may be +/- 1 depending on what month you were born in, and what month it is now!
<em>I hope this helps! :)</em>
Answer:
72
Step-by-step explanation:
A full rotation takes 360°. From the picture, it would take 5 rotations to achieve such full degree rotation. Hence, each bit of rotation covers 360°÷5=72°
