Substitute the given values into the formula, and solve for the unknown variable.
A=1/2h(B+b); A=21, B=2, b=5 h= ?

Respuesta :

Answer:

[tex]h=\frac{1}{6}[/tex]

Step-by-step explanation:

Given:

[tex]A=\frac{1}{2h} (B+b)\\[/tex]

[tex]A=21, B=2, b=5 ,h= ?[/tex]

We have to find the value of  'h'

So, putting the given values in the equation to find the value of 'h'.

          [tex]A=\frac{1}{2h} (B+b)[/tex]

Implementing the given values in the given equations:

         

                              [tex]21=\frac{1}{2h}(2+5)\\\\ 21=\frac{1}{2h} (7)\\\\\frac{1}{2h}=\frac{21}{7}\\\\ \frac{1}{2h}=3 \\\\h=\frac{1}{6}[/tex]

So, the value of 'h' is

                       [tex]h=\frac{1}{6}[/tex]
