Y=-7 Since we are adding, to find the answer we need to subtract. -2-5=-7
the answer would be a= -1
Answer:
64
Step-by-step explanation:
Here, we want to know the sum of the next two terms
We need to get the pattern first
The difference between the first two numbers is 49 (7^2)
next two is 36 (6^2)
next two is 25 (5^2)
next two is 16 (4^2)
next two will be 3^2 = 43-9 = 34
next will be 2^2 = 34-4 = 30
So the sum here is 30 + 34 = 64
Hi there! For this question, you need to know the ratio of sine and cosine.
- sinA = opposite/hypotenuse
- cosA = adjacent/hypotenuse
Define A = angle
opposite and adjacent side changes only if we focus on another angle.
From the picture, if we focus on angle S, the opposite would be 36. But if we focus on angle R (flip to make RT as base), see that the opposite would be 14.
Answer
- sinS = 36/42 = 6/7
- sinR = 14/42 = 1/3
- cosS = 14/42 = 1/3
- cosR = 36/42 = 6/7
The bold one is simplest form while the non-bold is non-simplest.
