Answer:
cos(A) ≈ 0.9165
Step-by-step explanation:
Put the given value into the given relation and solve for the unknown.
sin²(A) +cos²(A) = 1
(2/5)² + cos²(A) = 1
cos²(A) = 1 -4/25 = 21/25 . . . . . subtract (2/5)²
cos(A) = √(21/25) ≈ 0.9165 . . . . . take the square root
_____
Both sine and cosine are positive in Quadrant I, so we're only interested in the positive square root.
Answer:
100% if that's not an answer choice it is 1 because it is whole

p(9-4+5) = 0p = indeterminate
Step-by-step explanation:
there's no explanation, it's a simple concentration
The slope of the line is -1
X = 34
<span>2+8-x=-24
</span>Add 2 + 8: 10-x=-24
Subtract 10 from each side: -x = -34
Change the signs from each side: x = 34
