Let's find the value of x

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

therefore,

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

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

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

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

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

$\hookrightarrow \: x = 29\degree$

(1/4)^-2 - (5^0 x 2) x 1^-1 =

(4/1)^2 - (1 x 2) x 1 = 16-2 = 14

If you raise something to the power of -2, swap numerator and denominator and remove the minus.

So (1/4)^-2 = 4^2 = 16

Also 1^-1 is just 1, not -1.
