The sum of the lengths of the legs of a right triangle is 20 feet.a. If $x$ is the measure of one of the legs, represent the measure of the other leg in terms of $x .$b. If $y$ is the area of the triangle, express the area in terms of $x .$c. Draw the graph of the function written in $\mathbf{b}$ .d. What are the dimensions of the triangle with the largest area?

a) $20-x$b) $y=\frac{x(20-x)}{2}$c) See graphd) 10 $\mathrm{ft}$ by 10 $\mathrm{ft}$

starboard problem. 19. So this will see is that the right angle triangle given and its high protein yous is given by credits and tomatoes. We have to express the idea of the triangle. Attention affects which is not affects leg. So let's let this be X and B bye is the right angle triangle we control. Used by taco storms, we have X squared plus y sweaters 20 square. This means that we have X squared plus vice but US 400. This means that the value of ice was 400 minus X squared. Leighton's squadron Both sayings We have the value of y a square 400 minus six on We know that the idea offer a tangle of right angle triangles going by half times based times I explode remain X. But the value of why is this value by replaced by Sprint off 400 minus excess for So this is how 80 year authors, writing or trying, looks like just in terms. Offense
