Question

i found the value of x I need help finding the m<1 .

Answer 1

Given that

$x=5,$

you can use the facts that the sum of all the angles must be equal to 360° and that angles opposed by the vertex are congruent. You can set the following equation:

$2(m<1)+9(5)-28+5+12=360.$

Solving for m<1, you get:

$\begin{gathered} 2(m<1)+34=360, \\ m<1=\frac{360-34}{2}. \end{gathered}$

Finally, you get:

$m<1=163.$

Answer:

$163^{\circ}.$
