To solve for the missing angles, we need to apply the property of triangles below:

The sum of angles in a triangle is 180 degrees

a)


\begin{gathered} 68\text{ + 53 + x = 180} \\ 121\text{ + x =180} \\ x=59^0 \end{gathered}

Answer ; 59 degrees

b)


\begin{gathered} 46\text{ + 71 + x = 180} \\ 117\text{ + x = 180} \\ x=63^0 \end{gathered}

Answer: 63 degrees

c)


\begin{gathered} 24\text{ + x + x = 180} \\ \text{Collect like terms} \\ 2x\text{ = 156} \\ x=78^0 \end{gathered}

Aswer: 78 degrees
