Answer:
See below.
Step-by-step explanation:
A year has 12 months and 365 days.
3 months: 3/12 year = 1/4 year
55 days: 55/365 year = 11/73 year
1 month: 1/12 year
7 months = 7/12 year
120 days = 120/365 year = 24/73 year
Answer:
11.43
Step-by-step explanation:
Answer:
-√7/4
Step-by-step explanation:
Mathematically;
Sine is the ratio of opposite to hypotenuse
So here, hypotenuse is 4
The opposite is 3
To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the adjacent be x
4^2 = 3^2 + x^2
x^2 = 16-9
x^2 = 7
x = √7
The cosine is the ratio of the adjacent to the hypotenuse
Since we want to consider quadrant II
Cosine is negative here;
So the answer for Cos will be;
Cos theta = -√7/4
