5/4x-2=-1/4x+16 5/4x+1/4x=18 6/4x=18 x=12 y=13 choose a. (12,13)
Answer:
-cos(2A)
Step-by-step explanation:
We know that (a+b) (a-b) = a^2-b^2
So it means we can simplify to sin^2(A)-cos^2(A) and we know cos^2(A) - sin^2(A) = cos(2A) but we will just multiply by -1 and we get - cos(2A)
Answer:
4 is the answer....
Step-by-step explanation:
by putting the value of g and h, we get ;
- =》4 - ( 0.25 × 10 ) + ( 0.5 × 5 )
- =》4 - 2.5 + 2.5
- =》4
hence, the solution is 4
Given x = adjacent
10 = hypothenuse
Sohcahtoa (cah)
Cosine uses both adjacent and hypothenuse
x/10 = cos(37)
0.79863551 = x/10
x = 7.9763551
Solution: x = 8
