The object which are not luminous  are observed by the light reflected off the object and reaches our eyes.

Option B

<h3><u>Explanation:</u></h3>

A non-luminous object reflects light from its surface that is incident on it from some other luminous source or body, to be seen by the naked eye as a whole. The light reflected, reaches the observer’s eyes and is viewed as a result.

Non-luminous objects never emit their light, rather they are dependent on luminous objects to be seen by the observer. A piece of cloth, moon, earth, wood, plastics, metals, etc. are some fundamental examples of a non-luminous object.

Find the value of x if your answer is not an integer
kotykmax [81]

Answer: To solve such problems we need to know about Trigonometry.

Trigonometric functions

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

The value of x is 5√3.

Explanation: Given to us,

the base for the triangle, AB = 5 units,

Hypotenuse for the triangle, BC = 10 units,

∠B = 60°,

Solution

The question can be solved in two ways,

1.   Using the Pythagoras theorem,

According to Pythagoras theorem,

substituting the values,

2. using the trigonometric function for ∠B,

for ∠B in ΔABC,

substituting the values,

we know that value of tan(60°) is √3,

Hence, the value of x is 5√3.
