can u pls help in geometry for 100 points will also giv brainliest

We know
Hence
[tex]\\ \sf\longmapsto 3x+2x=90°[/tex]
[tex]\\ \sf\longmapsto 5x=90°[/tex]
[tex]\\ \sf\longmapsto x=18°[/tex]
We know
Diagonals of a rhombus intersect eachother at 90°
Hence
AB is the hypotenuse of a right angle traingle.
\begin{gathered}\\ \sf\longmapsto 3x+2x=90°\end{gathered}
⟼3x+2x=90°
\begin{gathered}\\ \sf\longmapsto 5x=90°\end{gathered}
⟼5x=90°
\begin{gathered}\\ \sf\longmapsto x=18°\end{gathered}
⟼x=18°
m<ABD=3(18)=54°
