5r + 6s = 53
25r + 3s = 49
Meaning of simultaneous is to solve by elimination
Multiply the equation 2 by -2
-2( 25r + 3s = 49)
-50r – 6s = -98
Then add the two equation to eliminate s, so the resulting equation is:
-45r =-45
r = 1
substitute r = 1 to equation 1
5(1) + 6s = 53
6s = 53 – 5
6s = 48

Using the law of sines to solve the triangle if..
Answer: No they don't because there is not way 1/3 can be multiplied by a number to get 2/9 and there is no way 2/9 can be divide by any number to get 1/3.

Answer:
Option B
Step-by-step explanation:
Given that cosθ = 
Since, θ is an angle in quadrant II therefore, cosine value is negative
Now we will find the tangent ratio from the given triangle.
tanθ = 
From the given triangle,
By applying Pythagoras theorem in the given right triangle,
AC² = AB² + BC²
AB² = 10² - 3²
= 100 - 9
= 91
AB = √91
tanθ = 
Now, tanθ = 
Since, θ is in second quadrant therefore, tangent of the angle will be negative.
tanθ = 
Option B is the answer.
