In a 45°-45°-90° triangle, the length of the hypotenuse is 11. find the length of one of the legs

7.78 or

Step-by-step explanation:

here we are given a right angle triangle , and in a right triangle , sum of squares of sides is equal to the square of hypotenuse.

This is right angle scalene triangle as the two angles other than right angle are 45° each.

Hence ,

in this case we have

Taking square roots on both sides

Here we have hypotenuse c given as 11

hence

Answer

the image of (6, 9) under a dilation is (4, 6). the scale factor is
