Answer:

Step-by-step explanation:

Since a cube has 6 sides, the surface area of a cube is 6 times the area of one of the sides. Therefore:

$SA=6\cdot 9^2=6\cdot 81= 486\text{ units}^2$

Hope this helps!

Write the equation of the line that passes through the given point and is perpendicular to the given line

Bumek [7]

Answer:

y = 5

Step-by-step explanation:

<u>The line x = 3 is parallel to y- axis, the perpendicular line is going to be parallel to x- axis and will have an equation:</u>

y = a

<u>Since it passes through the point (-2, 5), it will have a = 5:</u>

y = 5 is the line we need

An angle measures 12° less than three times it’s supplement. Find the measure of the angle

Butoxors [25]

Answer:

132 degrees.

Step-by-step explanation:

Let the supplement be x and the angle be y.

x + y = 180 degrees.

y = (3x - 12) degrees.

x + 3x - 12 = 180

4x = 192

x = 48 degrees

y = 132 degrees
