Question

Find the value of xx = 14x = 36x = 40x = 30

Answer 1

In a parallelogram the sum of two adjacent angles is equal to 180º.

Then, the sum of given angles is equal to 180º:

$127º+(17+x)º=180º$

Solve x:

$\begin{gathered} 127+17+x=180 \\ 144+x=180 \\ x=180-144 \\ x=36 \end{gathered}$

Then, the value of x is 36
