panjang pr adalah???? pakai jalan y tolonggg plisss banget

[tex] \frac{15}{15 + 12} = \frac{ \times }{ \times + 16} \\ \frac{15}{27} = \frac{ \times }{ \times + 16} \\ 15( \times + 16) = 27 \times \\ 15 \times + 240 = 27 \times \\ 240 = 27 \times - 15 \times \\ 240 = 12 \times \\ \times = 20 \\ pr \: = 20 + 16 = 36[/tex]

PT/TR = PS/SQ
PT/16 = 15/12
12PT = 240
PT = 240/12
PT = 20 cm

PR = PT + TR
PR = 20 +16
PR = 36 cm
