Answer:
It is not a right triangle
Step-by-step explanation:
A triangle has side lengths of 8 inches, 12 inches, and 16 inches.
To determine if it is a Right Triangle, we make use of the Pythagoras Theorem, i.e.
Now the Hypotenuse is always the longest side
The equality above is not true and in fact
Therefore the 3 numbers do not satisfy Pythagoras theorem and cannot be the lengths of a right triangle.
Answer:
3 = 9
4 = 10
Step-by-step explanation:
Answer:
option b
Step-by-step explanation:
sine all sides of a square are equal, AD = 8 too
therefore with pythagoras theorem,
AD^2 + AB^2 = BD^2
8^2 + 8^2 = BD^2
64 + 64 = BD^2
128 = BD^2
BD = root of 128 = 8 root 2 (b option)
Answer:
X=1 because 2+5=7 then X=1 cause 1*2=2
Step-by-step explanation:
Answer:
It should be C, I believe?
Step-by-step explanation:
The surface area of a sphere can be found by the formula: A=4πr²
If the area is 64 square feet. -----> square feet means doubled
A=64² = 4096 feet
4096 =4πr² (divide 4π on both sides)
4096 ÷4π = 1024π
1024π = r² (square root r on both sides)
r = 56.718523229
