<span>Kayla walks a path with a triangle shape with three corners, starting point A, point where turns north, B, and point where head towards start, C.
The question is calculate the angle in the point C, knowing that A-B distance is 4 km and B-C is 2.5
To do this calculation we are going to use the trigonometry function tangent:
tangent C = opposite/adjacent = 4/2.5 = 1.6
Then C angles is: C = arctan (1.6) = 57.99Âş
So the solution is round to 58Âş</span>
Answer:
Even function
Step-by-step explanation:
Both powers of x in f(x) = -3x^4 + 7x^2 are even, so f(x) = -3x^4 + 7x^2 is an even function.
It is definitely C: 20%
Subtract the original value from the new value, then divide the result by the original value then multiply the result by 100 and it will give you the answer
13 + [128 + (-24 - 5b)/2)]/3 - 45 = 0
(52 - 5b/2)/3 = 32
52/3 - 5b/6 = 32
14.67(6) = -5b
b = 88/-b
b= -17.6
