Answer:
y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
=
( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )
y = ≈ 61 ( to the nearest whole number )

Answer:
Step-by-step explanation:
So, we have the graph y=f(x).
And we want to find:
Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:
This means that we have the point:
So, to find our solution, we will swap the x- and y-coordinates. This gives us:
So, simply need to find the x-coordinate such that y is 0.
From our graph, we can see the point (6,0). In other words:
So:
And we're done!
