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

33. Scientists speculate that the first mammals related to the primates appeared during the Paleocene about years ago. A 50.000
Luba_88 [7]

Answer:

<u> B. 65 million</u>

Explanation:

  • Primates are remarkably the first mammals so when the earth formed about 4.5 billion years ago and the first life on earth dates to 3.5 billion years the primates did not appear before the 50-55 years ago.
  • Thus by the end of Mesozoic Era i.e about 65.5 million years ago, the primate started to have originated over the earth's surface. At that time the North American continent was still connected to the European landmass and India then was not a part of Asia and most of the landmasses had warm tropical or subtropical climates.
  • The body size of the early monkeys and apes that took the advantages of vast expanses of land and where the biggest animal to revolve around the 39-40 million years and flourished in the Oligocene Epoch.
