Find BD

Remember soh-cah-toa?

opposite/adjacent

tan30=400/x

xtan30=400

x = 400/tan30

Find BC

Still toa. . . still toa

90 + 60 = 150

180-150 = 30

BAC = 30

tan30=x/400

400tan30=x

BD-BC=CD

If you followed my steps, your answer should come to you.

If you didn't and are a lazy pr*ck who relies on others to do their semester exam problems for them, the answer is A. Or 461.

Answer:

A'''(1,1), B'''(-2,-1) and C'''(-4,0).

Step-by-step explanation:

Triangle ABC has vertices with coordinates A(-6,-1), B(-3,-3) and C(-1,-2) (from given diagram).

1. Translation the triangle ABC 5 units to the right and 2 units up has a rule

(x,y)→(x+5,y+2).

Then the image triangle A'B'C' has vertices A'(-1,1), B'(2,-1) and C'(4,0).

2. Reflection the triangle A'B'C' across the line y=-x has a rule

(x,y)→(-y,-x).

Then the image triangle A"B"C" has vertices A"(-1,1) (this point lie on the line), B"(1,-2) and C"(0,-4).

3. Rotation the triangle A"B"C" counterclockwise about the origin by 270° has a rule

(x,y)→(y,-x).

Then the image triangle A'''B'''C''' has vertices A'''(1,1), B'''(-2,-1) and C'''(-4,0).

Find the volume of the pyramid shown.

Gnesinka [82]

Answer:

Volume of the shown pyramid is 40 square centimetre.

Step-by-step explanation:

Given:- From given figure we can see that,

Base length of the pyramid (L) = 5 cm.

Base width of the pyramid (W)= 4 cm.

Height of the pyramid (H)= 6 cm.

To find:- Volume of the pyramid = ?

Solution:-

Let, Base length of the pyramid be L,

Base width of the pyramid be W,

and height of the pyramid be H

Now,

Formula for volume of pyramid = $\frac{Base\ length\times Base\ width\times Height\ of\ pyramid}{3}$

Volume of pyramid = $\frac{L\times W\times H}{3}$

Volume of pyramid = $\frac{5\times 4\times 6}{3}$

Volume of pyramid = $\frac{120}{3}$

Volume of pyramid = 40 sq.cm.

Therefore volume of the shown pyramid is 40 square centimetre.
