lenght= 2

breadth= 1

Length is a dimension to be measured in either in horizontal or vertical position and always longer than breadth.
Breadth is a dimension to measure in either in horizontal or vertical position and always lesser than length.
Dimension is a measurement of something in a particular direction, especially its height, length, or width.
In geometrical term demension is referred to length, breadth, and height
An object can be either 2d or 3d
circle, rectangle,square are 2 dimensional object while cube, cuboid,cylinder is 3 dimensional object
one dimensional object is practically not found but in theory we consider to solve questions.

The measure of angle A to the nearest tenth of a degree is: A 18.5 B 19.5 C 20.5

Andrew [12]

Answer:

B

Step-by-step explanation:

<u>This is a right triangle as shown by the right angle.</u>

The side opposite the right angle is the hypotenuse, which is 9.
The side opposite angle A is 3.

So we have the opposite of A and the hypotenuse.

The trigonometric ratio that relates opposite side to hypotenuse is SINE.

$sin\theta=\frac{opposite}{hypotenuse}$

Since, we need angle A, $\theta$ is A, opposite side is 3, and hypotenuse is 9, we substitute:

$sinA=\frac{3}{9}\\sinA=\frac{1}{3}$

<em>To solve for the angle, we use our calculator and find the inverse sin of $\frac{1}{3}$ :</em>

$A=sin^{-1}(\frac{1}{3})\\A=19.47$

<em>Rounding to nearest tenth of a degree:</em>

$A=19.5$

B is the right choice.
