First, some housekeeping:
cos = 12/13 is incomplete; "cos" must have an argument (input).
cos x = 12/13 is fine; here "cos" has the argument (input) x.
Given that cos x = 12/13, find sin x. To do this, we'll need to find the length of the opposite side, given that the hypo length is 13 and the adj. side length is 12.
12^2 + opp^2 = 13^2, or opp^2 = 169-144 = 25.
Then the opp side could be either 5 or -5. Let's assume that it's +5, and that angle x is in the first quadrant.
Then sin x = opp / hyp = 5/13 (answer)
cos 2 is an entirely different kind of problem. Here you are told what the argument (input) to the cosine function is (it is 2, which here means 2 radians).
Using a calculator: cos 2 = -0.416. Note that the angle 2 rad is in QII, which is why the "adjacent side" is negative and also why the cos of 2 is negative.
Answer:
x = -7
Step-by-step explanation:
Subtract 15 from both sides of the equation.
x = 8 -15 = -7
The first step you would take would be multiplying 5x2
A man's inheritance money = $1200
Given :
He shared his inheritance between his 3 sons in the ratio 1:3:6
Then, the money the first son got :
▪︎Thus, the first son inherited $120.
Money the second son got :
▪︎Thus, the second son inherited $360.
Money the third son got :
▪︎Thus, the third son inherited $720.
We know that :
The largest share = $720
The smallest share = $120
Difference between the largest and smallest share :
<h3> ●=> Therefore :</h3>
▪︎<em>The difference between the largest and smallest share = 600</em>
Answer:
The answer would be A. 1 1/5
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
