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

1 answer:

7 0

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

Answer:

A) Irrational, because it is not a terminating or repeating decimal.

Step-by-step explanation:

Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!
