Answer:
cosA = √(21/25)
Step-by-step explanation:
We know
sin²(A) + cos²(A) = 1
Next, we know that sin(A) = 2/5. Plugging that into our equation, we get
(2/5)² + cos²A = 1
4/25 + cos²A = 1
subtract 4/25 from both sides to isolate cos²A
cos²A = 1 - 4/25 = 25/25-4/25 = 21/25
square root both sides to get
cosA = √(21/25)
We do not include -√(21/25) in our possible answer for cosA because this is in quadrant 1, so cosA must be positive.

Answer:
y=0x+2 meaning the slope is equal to 0
Step-by-step explanation:
If you think about this question you'll see that our two points have the same y coordinate
This means that the slope is equal to 0
so we have
y=0x+b
If we plug in -3 for x and set the equation equal to 2 we can find b
0+b=2
b=2
so we have
0x+b=y
