Answer:
9.52 answer of third and all you answer are correct
Answer:
14/15
Step-by-step explanation:
Answer:
so 1/4 of a circle is 90 degrees 1/4 is equal to 90 over 360 C it's 90 parts of 360. so here we go with this one. this angle is 20 degrees remember that's 90 alright the square one and this little part would be 20 degrees each angle appears wider as the Rays get longer.
Step-by-step explanation:
Let me know if this help's you lol :)
We know that we can do
ab+ac=a(b+c)
so find common factor
factor them
27a=a times 3 times 3 times 3
21=3 times 7
common factor=3
3=a
27a/3=9a
21/3=7
so now we have
(3)9a+(3)7=3(9a+7)
The answer is = 1 + sin x
Explanation
we need
a^2 - b^2 = (a+b) (a-b)
we use
cos^2 x + sin^2 x = 1
cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )
therefore
cos ^2 x over 1 - sin x = 1+ sin x
