Answer:
25√2
Step-by-step explanation:
This is a 45-45-90 triangle
which means that the hyptonouse or AC is equal to x√2
we can write
50=x√2
x=50/√2
to rationalize this mulitply both sides by √2 to get
(50√2)/2= 25√2

Answer:
2
9/5
Step-by-step explanation:
2/1 = 2
18/10 (divide by 2 up and down) = 9/5
1. To find the length of the edge, you will divide the total distance of 36 cm between the 4 edges that are shown.
36/4 = 9 cm per edge.
2. To find the surface area, find the area of one square (9 cm x 9 cm = 81 square cm), and multiply it by 6.
81 square cm x 6 = 486 square cm
486 square cm is the surface area.
