Question

In the figure c // d.What are the coordinates of 1 and 2

Answer 1

`\angle1\text{ and }\angle2\text{ are supplementary angles}`
`\angle4=75^(\circ)(alternate\text{ angle)}`
`\begin{gathered} \angle4+\angle1=180(supplementary\text{ angle)} \\ 75+\angle1=180 \\ \angle1=180-75 \\ \angle1=105^(\circ) \end{gathered}`
`\angle2=75^(\circ)(\text{vertically opposite angle to }\angle4)`
