Answer:
volume = 13500 
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid = 
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume = 
= 
= 13500
volume = 13500 
The volume of the pyramid is 13500
.
False
because tan^2 45 = 1^2 = 1
and sec^2 x = 1/ cos^2 45 = (sqrt2)^2 = 2
so the sum = 3
Answer: x = -1, -3
