Answer:
Option C. 3√3
Step-by-step explanation:
Please see attached photo for brief explanation.
In the attached photo, we obtained the following:
Opposite = a
Adjacent = 3
Hypothenus = 6
Angle θ = 60°
We can obtain the value of 'a' as follow:
Tan θ = Opposite /Adjacent
Tan 60° = a/3
Cross multiply
a = 3 x Tan 60°
But: Tan 60° = √3
a = 3 x Tan 60°
a = 3 x √3
a = 3√3
Therefore, the length of the altitude of the equilateral triangle is 3√3.
Answer:
2.25 cm³
Step-by-step explanation:
The volume of a pyramid can be found using the formula:

Base area
= area of square
= side ×side
= 1.5²
= 2.25 cm²
Volume of paperweight
= ⅓(2.25)(3)
= 2.25 cm³
Area of triangle = 24cm
Area of rectangle = 120
therefore, w x 12 = 120
w = 10
I believe the answer is 9
Square root of 6 is 2.44 so place the dot at the the 2.4 place.
