Answer: Formula used for pyramid is (V= 1/3 Bh SA: 1/2 P*l+B) Final answer is SA=110.4 V=64
Step-by-step explanation:
P= Perimeter
l= length
B= Base
To find the perimeter you add all the sides of the base. (4+4+4+4)=16
To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse.
+
= ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
4+144=![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
164=![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
=x
x=12.8
To find the base it will be l*w (4*4)=16
Then you plug it in the formula for SA which will be
SA=1/2 16*12.8+16
SA=110.4
For Volume, it will be
V=1/3 Bh
V= 1/3 16(12)
V= 64

Step-by-step explanation:
Answer:
(A) 21
Step-by-step explanation:
5x-15 needs to equal 90 since it is a right angle and 21 makes that true
![(5*21)=105\\105-15=90](https://tex.z-dn.net/?f=%285%2A21%29%3D105%5C%5C105-15%3D90)
