Answer 1

If triangle ABC is a right triangle and

A half circle has 180 degrees, so the sum of
`\begin{gathered} 90\text{ + (}x\text{-12)}+x\text{ = 180 } \\ x\text{ - 12 + x = 180 - 90 } \\ 2x\text{ - 12 = 90} \\ 2x\text{ = 90 + 12} \\ 2x\text{ = 102} \\ x=\text{ 102/2 } \\ x=\text{ 51º} \end{gathered}`So, if x= 51º, then m
