The answer gives it straight forward but explanation gets in depth
Edit: I saw your answer and yes it equals 10 but you multiply what it is a fraction of too.
2/3
x5
10/15
Hope that helps some more
Recall the following formula:
Given a triangle with side lengths a, b, and c. Let the measure of the angle between sides of length a and c be B.
Then, the area of the triangle is given by :

.
In our example we have: Area=10 square cm, a=8 cm, c=5 cm, and we want to find the measure of the angle between the 2 sides a and c.
Substituting in the formula we have:

Thus,

, which means

.

is the sine of

, but also

.
