What is the slant height of a square pyramid with the height of 10cm and base edge 20cm

Klio2033 [76]

Hello!

To find the base length you use the Pythagorean Theorem

$a^{2} + b^{2} = c^{2}$

c is the slant height
a is half the base length
b is the height

Put in the values you know

$10^{2} + 10^{2} = c^{2}$

Square the numbers

$100 + 100 = c^{2}$

Add

$200 = c^{2}$

Take the square root of both sides

$c = \sqrt{200}$

Simplify

$c = 10 \sqrt{2}$

Hope this helps!

The GFC of an odd and even number is always odd True or False?

OLga [1]

I think you mean GCF, or greatest common factor, in which case, yes, this is always true. An odd number has no factors of 2 or multiples of 2, so there is no way a factor of an odd number can be divisible by 2. Even if the even number has no odd factors, That would simply mean they have no common factors greater than 1, so the GFC would just be 1.
