<span>When a river start its normally at a glacier and as it goes down its course the water temp tends to rice, you see more aquatic life and it either gets more or less water flowing in to it like other water sources go in to it or it brakes off in two directions </span>

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

$\blue\star$ we 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> $\blue\star$ Now 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
