Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

$\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree$

$\hookrightarrow \: 2x - 2 \degree + x + 5\degree = 180\degree - 90\degree$

$\hookrightarrow \: 3x + 3\degree = 90\degree$

$\hookrightarrow \: 3(x + 1) = 3(30)$

$\hookrightarrow \: x + 1\degree = 30\degree$

$\hookrightarrow \: x = 29\degree$

Crank

$(1 - 3k) + (2 + 2.5k)$

$= 1 - 3k + 2 + 2.5k$

$= (1 + 2) + ( - 3k + 2.5k)$

$= 3 + ( - 0.5k)$

$= 3 - 0.5k$
