Answer:
2.33 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = AC / BC
tan 25 = AC / 5
Multiply each side by 5
5 tan 25 = BC
2.331538291 = BC
To the nearest hundredth
2.33 = BC
21 is 30% of 70. 70*.30=21
The volume of a pyramid is expressed as the product of its length, width and height divided by three. We first solve the volume of pyramids A and B.
Volume of A = (10 x 20 x h) / 3 = 200h / 3
Volume of B = (10 x 10 x h) / 3 = 100h/3
Since the heights of the two pyramid are the same we can substitute on equation to the other in terms of h.
Volume of A = (200 x 3 x Volume of B) / (100 x 3)
Volume of A = 2 x Volume B
Thus, the volume of A is twice the volume of B.
If the height of pyramid B is twice of pyramid A, the new volume of pyramid B is equal to the volume of pyramid A.
