First blank: sin. C = h/a
The ratio for sin. is opposite (the height) over hypotenuse (a).
Second blank: Area = (1/2)b(a sin. C)
In this substitution, we are substituting the value of h into the traditional area of a triangle formula.
Third Blank: Area = (1/2)ab(sin C)
We are using the commutative property to move the position of a.
Hope this helps and good luck in your classes!
Answer:4.265
Step-by-step explanation:
Can it be decimal?
Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
