Here we are given
angle S = 70°
RS= 5cm
Now we know that ,
[tex]tanx=\frac{Perpendicular}{Base}[/tex]
Here angle x is 70 degrees and Base RS is 5 cm.
Also Perpendicular is QR, which we have to solve for,
Plugging these values in the formula above,
[tex]tan(70)=\frac{QR}{5}[/tex]
[tex]2.74747742=\frac{QR}{5}[/tex]
QR=13.735cm
QR=14cm(approximately)
Answer: QR= 14 cm (option D)
