Answer:
- given leg: 2400 ft
- other leg: 1000 ft
- hypotenuse: 2600 ft
Step-by-step explanation:
The Pythagorean theorem tells a relation between the leg lengths and the hypotenuse. If x represents the unknown leg length, then we have ...
x^2 + 2400^2 = (x +1600)^2
x^2 +5760000 = x^2 +3200x +2560000 . . . . eliminate parentheses
3200000 = 3200x . . . . . . . . . subtract x^2+2560000
1000 = x . . . . . . . . . . . . . . divide by 3200
The other leg length of the garden is 1000 ft. The garden is a triangle with side lengths 1000 ft, 2400 ft, 2600 ft.
Answer:
24 square units
Step-by-step explanation:
6×4=24
1. A = 2ab + 2ac = 2bc
2. A = 2b(a +c) + 2ac
3. 2b(a + c) = A - 2ac
4. b = (A - 2ac) / 2(a + c)
The area is A=1/2aP
a=apathem
p=perimeter
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
