25-(2+5)(2+5)
25- 4+10+10+25
=66
Answer:
92 1/12
Step by step explanation:
Pi is an endless number so it can be anything
ex: 6.3754285187654156784617592358041678236585372072548
and so on
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.
Answer:
Option A is the correct answer.
Explanation:
Let A be the base area and h be the height of prism.
Volume of prism = Base area x Height = a x h =ah
Now we have base area of pyramid = Base area of prism = a ( both have same type of base)
Height of pyramid = 3 x height of prism = 3h
Volume of pyramid = 1/3 x Base area x Height = 1/3 x a x 3h = ah
Comparing both volumes, we will get Volume of prism = Volume of pyramid
So their ratio is 1.
Option A is the correct answer.
