What is a cuboid?

A cuboid is a three-dimensional shape in which all sides are rectangles. A cuboid has 6 faces, 8 vertices, and 12 edges. All the angles formed at the vertices of a cuboid are right angles. The opposite edges are parallel to each other.

For the given situation,

The rectangular plant holder is in the shape cuboid.

Length of the rectangular plant,l = 8 inches

Width of the rectangular plant,w = 7 1/2 = 15/2 inches

Height of the rectangular plant,h = 5 inches

The formula of volume of cuboid is

[tex]V=lwh[/tex]

⇒ [tex]V= (8)(\frac{15}{2} )(5)[/tex]

⇒ [tex]V=300[/tex]

Hence we can conclude that the rectangular plant can hold the volume of potting soil is 300 cubic inches.

In ΔMNO, n = 92 inches, ∠N=119° and ∠O=20°. Find the length of m, to the nearest 10th of an inch.

Answers

Answer:

Step-by-step explanation:

The length of the side of the triangle will be 69 inches.

What is the sine law?

The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.

The sine law in the triangle ΔMNO is given as,

n / sin N = m / sin M = o / sin O

The third angle is calculated as,

∠M + ∠N + ∠O = 180°

∠M + 119° + 20° = 180°

∠M = 41°

The length m is calculated as,

n / sin N = m / sin M

92 / sin 119° = m / sin 41°

m = 69 inches

The length of the side of the triangle will be 69 inches.

A -foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a angle with a short vertical support.

Answers

Complete question :

A 25-foot-long footbridge has two diagonal supports that meet in the center of the bridge. Each support makes a 65∘ angle with a short vertical support.

What is the length x of a diagonal support, to the nearest tenth of a foot?

Answer:

13.80 feets

Step-by-step explanation:

Taking either of the triangles formed and attached to the picture, the length of diagonal, x can be obtained using Pythagoras rule :

To obtain x :

Sinθ = opposite / hypotenus

Opposite = 12.5 feets ; hypotenus = x ; θ = 65°

Sin 65 = 12.5 / x

0.9063077 * x = 12.5

x = 12.5 / 0.9063077

x = 13.792225

x = 13.80 feets
