What is the measure of ∠uvs? a) 39° b) 78° eliminate c) 102° d) 141°

39

Step-by-step explanation: The solution is 39°. The measure of the inscribed angle is half the measure of the intercepted arc.

m∠UVS =  

1

2

(78) = 39°

B) Test the material in controlled natural settings by using natural UV light, and measure the UV light that passes through.  

Ultraviolet rays are radiations from sun that the earth receives. These radiations have a direct impact on human skin, these are able to cause mutations in human genome and are carcinogenic in nature. A lightweight material can be tested in controlled natural settings by using natural UV light like skin cells can be observed under two conditions. In controlled condition a skin cell which is not coated with light weight material and in experimental skin cell which is coated with lightweight material.  If these cells are exposed to different ranges of UV radiations will help in deducing important conclusion regarding the usefulness of light weight material in blocking sunlight. The controlled cell will die because it is not tolerant to UV rays. The experimental skin cell will either survive or die. If it survives then, it can be concluded that the light weight material is effective in blocking UV rays and if it dies then, a light weight material is not effective in blocking UV rays.

Therefore, testing the material in controlled natural setting by using natural UV light, and measures the UV light passes through would be the most helpful method for testing the material.

(B)

Step-by-step explanation:

Given: A circle with intercepted arc is .

To find: The measure of ∠UVS.

Solution:

Since, we know that the angle made of the inscribed angle is half of the intercepted arc, therefore

           (1)

We are given that A circle with intercepted arc is , thus equation (1) becomes:

Therefore, option B is correct.

i accidentally posted this empty

i meant to ask if there was an image attached

sorry bout that

Step-by-step explanation:

Test the material in controlled natural settings by using natural UV light, and measure the UV light that passes through.

Explanation:

Because i'm a savage

The answer is 39 degrees

Explanation:

The answer would be the second option

B. Test the material in controlled natural settings by using natural UV light, and measure the UV light that passes through

The correct answer is statement B.

Explanation:

The UV rays refer to the radiation emitted from the Sun, which the Earth receives. These radiations exhibit a direct influence on human skin, these possess the tendency to produce mutations in human genome and are carcinogenic in characteristic.  

A lightweight substance can be examined in controlled natural environments with the application of natural UV light, like the skin cells that can be observed under two conditions, that is, in controlled condition, in which a skin cell is coated with lightweight material, and in experimental condition, in which skin cell is coated with lightweight substance.  

After exposing these cells to distinct ranges of UV rays, it will assist in finding an important conclusion considering the benefit of the lightweight substance in obstructing sunlight. The controlled cell will die as it is not able to withstand UV rays, while the experimental skin cell will either die or survive.  

In case, if it thrives then it can be deduced that the lightweight substance is efficient in preventing ultraviolet rays, and if it dies, then a lightweight substance is not efficient in preventing UV rays.  

Thus, testing the substance in a controlled natural setting by utilizing UV light, and measuring the UV light passing through would be the most appropriate approach for examining the substance.  

The correct answer would be option B.

Explanation:

Ultraviolet rays or Uv rays are radiations from the sun. Such radiations have a bad impact on skin, they can cause mutation and make it carcinogenic or simply burn the skin.

The lightweight material can be tested in a controlled natural setting by placing in two samples one without lightweight material and other with it and measure result in the natural UV light than measure in UV light that passes through.

Analyzing the test result would help in testing the material if it is effective with UV rays or not

Thus, the correct answer would be option B.
