An equilateral triangle has three 60 degree angles.
The altitude divides it into two 30 60 90 triangles.
The altitude is the "middle side" of such a triangle.
When that is the case, the middle side divided by the square root of 3 = the short side and multiplied by (2/sq root (3)) equals the hypotenuse.
The hypotenuse is the side of the equilateral triangle.
So, 6 * 2 / (sq root of 3) =

Answer:
A cube or a cuboid.
Step-by-step explanation:
A cube or a cuboid is a three dimensional shape that has
12 edges, 8 corners or vertices, and 6 faces.
The difference between a cube and cuboid is that a cube has all edges equal which makes every face a square while a cuboid has two square faces and four rectangular faces.

A. 189,600
Step-by-step explanation:
(79×60)×5=23700
23700×8=189600
Since you didn't give the actual equation, I can only help with the mean of each part.
Q1: The coefficient of x is called the slope. That is the number in front of the x.
Q2: The constant term is the y-intercept. That is the number at the end of the equation.
Answer:
m∠2 = 113º
m∠3 = 67º
Step-by-step explanation:
m∠2 is supplementary to m∠1, meaning if you add them to m∠1, you will get 180º.
m∠2 + m∠1 = 180º.
m∠2 + 67º = 180º
m∠2 = 113º
m∠1 and m∠3 are vertical angles and are therefore the same.
