Answer:
x = 3
Step-by-step explanation:
Since the triangle is isosceles then the 2 legs are congruent, both x
Using Pythagoras' identity in the right triangle
x² + x² = 6²
2x² = 36 ( divide both sides by 2 )
x² = 18 ( take square root of both sides )
x = = = × = 3

Answer:
length 8 feet and width 8 feet
Step-by-step explanation:
Lets x be the length and width of the sheet
An open box is to be constructed from a square piece of sheet metal by removing a square of side 2 feet from each corner
so height is 2 feet
length of the box is x-4 feet
width of the box is also x-4 feet
Volume of the box is length times width times height
divide both sides by 2
take square root on both sides
Add 4 on both sides
So dimension of the sheet is
length 8 feet and width 8 feet
Since they make 48.8 liters for each minute, and they want to know how many liters will they make in 7.2 minutes. All you would need to do is multiply 48.8 x 7.2 = 351.36 and that would be your answer.
Hope it helped !
