<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

Briefly compare and contrast the two disciplines, geography and geology
jarptica [38.1K]

The main difference between geography and geology is that geography is mostly dealing with the physical overall shapes of the land. Geology is a science that is interested in how the land got into the shape it did.

Geology is mostly about what the ground is made up of from a natural perspective. What kind of rocks it contains and how those rocks or layers of rocks got there.

Geography is mostly dealing with mapping the extent of landforms, how far rivers are, how long mountain ranges are, how long the coast line is. This is often from the perspective of people or culture.
