Answer:

A. 264m^2

Step-by-step explanation:

Base SA = 8 x 9 = 72

Back SA = 6 x 9 = 54

Side SA = 1/2 (8 x 6) = 24

Front slope SA = 9 x 10 = 90

TSA = 72+ 54+24+24+90 = 264m^2

Find the distance between (2,7) and (-6,-2)

stepladder [879]

Answer: $\sqrt{145}$

Step-by-step explanation:

1. use the distance formula!

$distance = \sqrt{(x_{2} - x_{1})^{2} +{(y_{2} - y_{1})}^2$

2. then using the distance formula with (2, 7) and (-6, -2) you get...

$distance= \sqrt{2 -(-6)^2 +(7 - (-2)^2}$

$distance= \sqrt{8^2 +9^2}$

$distance= \sqrt{64 +81}$

$distance= \sqrt{145}$

$\sqrt{145}$ is the simplest radical form

Which types of polygons are the faces of a tetrahedron?

valentina_108 [34]

The answer is the option A, which is: A. Equilateral triangles.

The explanation for this answer is shown below:

By definition, a tetrahedron is a solid in three dimensions that has: six sides, four vertices and four triangular faces. These faces are equilateral triangles, which means that all the sides are equal and all the interior angles measure $60$ degrees.

The tetrahedron is also called "triangular pyramid".
