Help with question on Complementary and Supplementary Angles

Mathematics
1 answer:
stiks02 [169]3 years ago
8 0

Step-by-step explanation:

Right angle = 90°

(x + 3) + (x - 1) + (x + 1) = 90

3x + 3 = 90, x = 29.

Supplementary angles = Angles that add up to 180°.

x + (x + 104) = 180

2x = 76, x = 38.

G(x) = x3 + 6x2 + 12x + 8<br><br><br><br> Determine the function’s value when x = −1.
salantis [7]

Answer:

g(-1) = 1

Step-by-step explanation:

Synthetic division is by far the fastest way to evaluate this function at x = -1.  Set up synth. div. as follows:

-1   )   1    6    12    8

              -1    -5    -7

     ----------------------

         1     5     7     1                

since the remainder is 1, g(-1) = 1

The volume of a pyramid that fits exactly inside a cube is 49 cubic feet. What is the volume of the cube?
Gekata [30.6K]
If the pyramid fits perfectly in a cube, this means that its base is a square and its height has the same value as the side of the square. Let x be the measure of the sides of the cube. The volume of the cube (Vc),
                                    Vc = x³   ; 49 ft³ = x³    ; x = 49^(1/3)

The volume of the pyramid is,
                                Vp = (1/3)(x²)(x) = (1/3)(x³)
Substituting the known values,
                                 Vp = (1/3)((49^(1/3))³ = 16 1/3 ft³

Thus, the volume of the pyramid is approximately 16.33 ft³.
