Answer 1

Answer:

As we know that sum of three angles of triangle is 180º.

$\blue\star$ we have

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

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

$\blue\star$ The angles a and c are equal so,

cb = ab. [ sides opp to equal angles are equal]

so x is also 16

$\blue\star$ Now we have two side we can easily find the third side by P.G.T

${AC}^(2)$ = ${BC}^(2)$ + ${AB}^(2)$
${AC}^(2)$ = ${16}^(2)$ + ${16}^(2)$
{AC}= $√(512)$

so the r is root 512 and x is 16.

Hope it helpa
