In the diagram below, OL is perpendicular to DX.<br>Pro<br>No 13<br>Tea<br>Find the length of OX​
lubasha [3.4K]

Answer:

Line OX = 7.09

Explanation:

The question is incomplete. Find attached the complete question.

SOLUTION

Given:

Line OL is perpendicular to DX

Line DX = 13

Line PO = the hypotenuse of the larger triangle

Line PO = 10

Line BO = hypotenuse of smaller triangle

Line BO = 12

To find length of line OX, we would apply rule of similar and congruent triangles.

∆DPO = ∆XBO

<POD = <BOX

Line DP is parallel to line XB

Since length of side DX = 13

Side DX = side DO + side OX

Let side DO = x

Side OX = 13-x

(Adj of ∆DPO)/(Adj of ∆XBO) = hyp of ∆DPO/hyp of ∆XBO

DO/OX = PO/BO

x/ (13-x) = 10/12

12x = 10(13-x)

12x = 130-10x

12x +10x = 130

22x = 130

x = 130/22 = 65/11

x is approximately = 5.91

Therefore line OX = 13 - 5.91

Line OX = 7.09

olga nikolaevna [1]

Areas are the geographic object of a geographic information system (gis) that is most likely used to show a particular zip code or a large tourist attraction.

A Geographic information system (GIS) is a laptop device that analyzes and presentations geographically referenced facts. It uses information that is attached to a completely unique location.

A geographic information system is a type of database containing geographic data, blended with software program tools for handling, reading, and visualizing those records.

An example of this kind of information is pc information amassed by satellites that show land use the place of farms, towns, and forests. remote sensing provides every other device that may be incorporated into a GIS. Far-off sensing consists of imagery and different statistics collected from satellites, balloons, and drones.

Mamont248 [21]

Answer:

Question 14. Option b

Question 15. Option a

Question 16. option c

Explanation:

Question 14.:

Regardless of the heaviness of the Ash particles inside it blended with the hot volcanic gases, this is the light comparative with the cold encompassing air.

It rises convectively over the thrust area and is known as the convective ascent region of the emission section.

Question 15.:

Since the gravity isn't so solid on Mars and Mercury Lava streams can be thicker as a result of which they don't cool so quick when contrasted with the earth. Little cone volcanoes on Mars would tend to be in general more extensive and shorter.

Question 16.:

Cryovolcano is otherwise called the ice spring of gushing lava. What's more, cryovolcanism is a method where the ejection of magma from ice happens as opposed to rock in molten form. Cryo Magma or the cryo magma or ice volcanic liquefy are normally fluids or vapor.
