Question 1061662
Find the height {{{h}}}.
You know that the hypotenuse of a right triangle is {{{10}}} and one leg is {{{h}}} and the triangle is isosceles since the angle is 45.
{{{10^2=h^2+h^2}}}
{{{2h^2=10^2}}}
{{{sqrt(2)h=10}}}
{{{h=10/sqrt(2)}}}
{{{h=5sqrt(2)}}}
So then,
{{{A=bh}}}
{{{A=10*5sqrt(2)}}}
{{{A=50sqrt(2)}}}
