Question

Need help with 9 and 11. Short questions won’t take a lot of time

Answer 1

We will have the following:

9.

From the information provided we can obtain the following:

We know that m<3 = 75°.

m<12 = 35°, but by corresponding angles m<4 = m<12 = 35°.

Then:

`\begin{gathered} m<3+m<4+m<5=180\Rightarrow75+35+m<5=180 \\ \\ \Rightarrow m<5=70 \end{gathered}`

Now, by opposite angles we have that m<5 = m<8 = 70°.

11. We will have the following from the information provided.

We know that m<3 = 75° and by corresponding angles m<3 = m<1 = 75°.
