The area of a triangular sail is given by the expression 1/2bh, where b is the length of the base and hi is the height. what is the area of a triangular sail in a model sailboat when b=12 inches and h=7 inches?

42 square inches.

Step-by-step explanation:

The given expression for the area of the triangular sail is

Here b is the length of the base and h is the height.

Now, we have to find the the area of a triangular sail in a model sailboat when b=12 inches and h=7 inches.

Substituting these values in the above expression to find the area of the triangular sail.

Therefore, the area of  triangular sail in a model sailboat when b=12 inches and h=7 inches is 42 square inches.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
