VX is 43° due to that the angle is on the outside and the last two arcs come to be 96° times two plus 125° and 43° all equals 360°.
Okay so, to get C you add the ones inside the triangle together.
42+58=100 Then the last angle will be 80, because when you add the three inside the triangle, you should get 180
42+58+80=180
To get D, you have to subtract 180 and 58, because 58+d will be a straight angle.
180-58=121
To get B and A, you would also have another straight angle (c, b, and a)
180-80=100
I believe that B=A, so, with the remaining 100, both A and B equal 50.
50+50+80=180
Does this help??
Answer:
f(4) = 3
When f(x) = 4, x = -1
Step-by-step explanation:
f(4) states that x co ordinate= 4. We need to find the y -co ordinate when x =4;
From the graph, when x = 4 , f(4) = 3
When f(x) = 4 , the x - co ordinate is -1
<span>Answer is C.
Explanation :-
Take the 1st case where Number of student(n) = 3 and Cost per student(c) is 24, we get n*c = 72
Take the 2nd case n = 6 and c =12, we get n*c = 72
Take the 3rd case n = 9 and c = 8, we get n*c = 72
By above observation we can say that product of Number of student and cost per student is 72 always.
Now for n = 12 we have to calculate c
n*c = 72
c = 72/12 = 6.
hence answer is option C.</span>
