The given figure can be drawn as,
From the figure,


Since angle of incidence will be equal to angle of reflection,
Therefore, the height of cactus is 6 m.
Hello!
You always think of these graphs out of 100%. As you can see, the blue takes up about half of he graph. Half of 100 is 50.
Therefore, our answer is D) 50%
I hope this helps!
(-1)+(-6)= -7
-7 + 6 = -1
therefore, the answer is 6.

Hello!
We are going to use the rectangular prism of the image as a guide:
First of all, the AC segment is calculated using the Pythagoras' theorem:

(A) The surface area of a prism is the sum of the surface areas of each face.
For the 2 triangles ABC and DEF

For the ABEF Rectangle

For the ACDE Rectangle

For the BCDF Rectangle

To finish you need to sum up the areas of each face:

(B) The volume of a prism is the product of the area of its base and the height of the prism. In this case, the base is a triangle so the formula and the calculations for the volume are as follows
