Question

so I think I got nine correct but 10-11 are part of the same problem and I'm not sure to go from here

Answer 1

`\begin{gathered} 10.\text{ }(\angle1+\angle3)+90^(\circ)+17^(\circ)=180^(\circ) \\ \Rightarrow(61^(\circ)+\angle3)=180^(\circ)-90^(\circ)-17^(\circ) \\ \Rightarrow\angle3=73^(\circ)-61^(\circ) \\ \Rightarrow\angle3=12^(\circ) \end{gathered}`
`\begin{gathered} 11. \\ \Rightarrow\angle2+\angle3+17^(\circ)=180^(\circ) \\ \Rightarrow\angle2+12^(\circ)+17^(\circ)=180^(\circ) \\ \Rightarrow\angle2=180^(\circ)-29^(\circ) \\ \Rightarrow\angle2=151^(\circ) \end{gathered}`
