Find the area of the given triangle to the nearest square unit. angle a= 30 degrees, b=10, angle b=45 degrees

Step-by-step explanation:

Suppose we have a general triangle like the one shown in the figure.

We know the angle A, the angle B and the length b.

By definition I know that the sum of the internal angles of a triangle is always equal to 180 °.

So

We solve the equation and thus we find the angle C.

We already know the three triangle angles.

Now we use the sine theorem to calculate the sides c and a.

The  sine theorem says that:

Then

Also

Finally, we use the Heron formula to calculate the triangle area

Where s is:

Therefore

the answer is c just got it on ed
