The base of a right triangle is 1 foot, and the interior angles are 45-45-90. what is its area?

As you see from the figure on the right, two 45-45-90 triangles together make a square, so the area of one of them is half the area of the square. As a formula.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
