The area a of a triangle is given by the formula a=1\2 bh where b is the base and h is the height : solve the formula for the height

h=2A/b

Step-by-step explanation:

A=1/2bh

Isolate h by moving 1/2 and b to the other side of the equation.

Divide each side by 1/2,which is multiplying by 2, which gives you 2A=bh.Now divide each side by b, which gives you 2A/b=h. Turn it around.

2A/b=h becomes h=2A/b

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.
