Answer:
In a 45 - 45 - 90 triangle, the legs are equal and the ratio of sides from shortest to longest is 1 : 1 : √2 where 1 are the legs and √2 is the hypotenuse. In this case the leg is 10 / √2 = 5√2.
Answer: A. Just took my best guess
Answer:
Step-by-step explanation:Include both the dimensions of the new boxes, as well as a verbal description of how the reams will be packaged. You may include sketches if you wish.
Congruent means that they are identical
looking at the order of the letters in the triangles EF are the last 2 and QR are the last 2
so EF should equal QR
we are told QR = 10 so EF needs to equal 10
so we have 6y+4 = 10
now solve for Y
6y +4 = 10
subtract 4 from each side:
6y = 6
divide each side by 6
y = 1
