(Look at the graphs for questions 1 and 2.)
1 answer:
Solving Q1 : What is y when x = 50? (the solution graph is attached below)
We can make a rectangle (in red color on solution graph) to find the value of y corresponding to x = 50. We can see that y-value lies between 200 and 250.
It is near about y = 225. Hence, option B is correct.
Solving Q2 : What is x when y = 300? (the solution graph is attached below)
We can make a rectangle (in red color on solution graph) to find the value of x corresponding to y = 300. We can see that x-value lies between 60 and 65.
It is near about x = 61. Hence, option A is correct.
Solving Q3 : Solve 17x = 3.
Hence, option A is correct i.e. x = 0.18

Answer:
(–5, 12) is the correct answer.
Step-by-step explanation:
We are given the following values:
Now, we know the following identities:
Now, the values are:
Sine value is positive and cos, tan values are negative.
It can be clearly observed that is in 2nd quadrant.
2nd quadrant means, the value of will be negative and
will be positive.
Let us have a look at the value of :
Please refer to the attached image for clear understanding and detailed explanation.
Hence, the correct answer is coordinate (x,y) is (–5, 12)
