Todd's yard is 22ft by 21ft. He is putting in a pool that measures 9ft by 12ft. After he installs the pool, he must pour concrete around the rest of the yard. How
much concrete does he need?

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
