Tolong di jawab ya yg gambar 2 segitiga tersebut

10.
PT bersesuaian dg PQ=PT/PQ=PT/PS+SQ=4/6+SQ
PS bersesuaian dg PR=PS/PR=PS/PT+TR=6/4+8=6/12=1/2
Jadi,
PT/PQ=PS/PR
PT/PS+SQ=PS/PR
4/6+SQ=1/2
1(6+SQ)=4×2
6+SQ=8
SQ=8-6
SQ=2

11.
BD=9
CD=16
Maka, BC=BD+CD=6+19=25

AC²=CD×BC
AC²=16×25
AC²=400
AC=√400
AC=20

AB²=BD×BC
AB²=9×25
AB²=225
AB=√225
AB=15

AD²=BD×CD
AD²=9×16
AD²=144
AD=√144
AD=12

Semoga bisa membantu...
