Kay [80]3 years ago

Answer:

There are approximately 66666 astronimic units in a light year

Explanation:

This is a simple exercise of ratios.

Since the astronomic unit is 1.5e8 km and the light year is 10^13 km (the question had an error) we can write:

1 = \frac{x * AU}{1 LY}

So:

x = \frac{1 LY}{1 AU} = \frac{1e13 km}{1.5e8 km} = 666666

<h3>As we know that sum of three angles of triangle is 180º.</h3>

\blue\starwe have

angle \: a + angle \: b+ angle \: c= 180 \\

a + 45 + 90 = 180 \\ a = 180 - 135 \\ a = 45

<h3>\blue\star The angles a and c are equal so,</h3>
  • cb = ab. [ sides opp to equal angles are equal]

so x is also 16

<h3>\blue\starNow we have two side we can easily find the third side by P.G.T</h3>
  • {AC}^{2} = {BC}^{2} + {AB}^{2}
  • {AC}^{2} = {16}^{2} + {16}^{2}
  • {AC}= \sqrt{512}

<h3>so the r is root 512 and x is 16.</h3>

Hope it helpa

What type of rocks can be metamorphosed? Select one: a. Sedimentary rocks O b. Metamorphic rocks O c. igneous rocks o d. All roc
zubka84 [21]

Answer:    B. Metamorphic rocks  

Explanation:  Metamorphic rocks are those that have undergone changes due to extreme heat and pressure. Thus, the rock, from which it becomes a metamorphic rock, is heated at temperatures above 150-200 ° and exposed to a pressure of 1500 bar.  In this way, the structure of the rock is changed, in terms of the arrangement of the atoms, and the result is a change of physical and chemical properties. There are two basic types of metamorphic rocks: foliated and slate. Generally, some of the metamorphic rocks are anthracite, schist, quartzite, marble, etc.

<span>Wegener had the evidence that there are similar rock formations on different continents and that the shape and rock formations of continents on either side of an ocean fit quite nicely. However, he could not find the mechanism that caused the continents to move across the ocean floor. I hope this helps. :)</span>
