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=(360-34)/(2). \end{gathered}`

Finally, you get:

`m<1=163.`

Answer:

`163^(\circ).`
