First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.
So we will get
Now we use sine law, which is
Substituting the values, we will get
The formula of area of triangle, for the given triangle is
I think it would be two solutions
Answer:
Step-by-step explanation:
The general equation for a parabola in vertex form is the following:
Where () is the parabola's vertex and (a) is the stretch and compression factor. As one can see in the given graph, the parabola has a vertex at (0, 1), moreover, it passes through the point (1, 3). Substitute these points into the equation for the parabole, and simplify,
Vertex: (0, 1)
A point on the parabola: (1, 3)
Inverse operations,
Substitute back into the original expression:
Simplify to put in standard form:
