Does anybody know this

Since the triangle is a right triangle we can use the triangle pulled out of the pyramid to solve for the height.

Height = 15 ft

Step-by-step explanation:

using Pythagorean theorem:

= 15

15

Step-by-step explanation:

The perimeter of a triangle can be represented as a^2+b^2=c^2

so we can put in the numbers to make it 8^2+b^2=17^2

or 64+b^2=289

so we can do

289-64=b^2

225=b^2

=

15=b
