Question

Need help writing the paragraph proof based on information given

Answer 1

Given:

`\angle A\cong\angle BDA`

From the image,

`\begin{gathered} \angle A=5x \\ \angle BDA=3x+30 \end{gathered}`

Paragraph proof:

`\begin{gathered} Since\text{ it is given that }\angle A\cong\angle BDA,\text{ and }\angle A=5x,\angle BDA=3x+30,\text{ then:} \\ \begin{equation*} \angle A\cong\angle BDA \end{equation*} \\ 5x=3x+30 \\ 5x-3x=30 \\ 2x=30 \\ x=(30)/(2) \\ x=15 \end{gathered}`

Prove:

x = 15
