BC+CA=23
BC-CA=7
THEN,
BC=7+CA
PUT IN IST EQUATION
7+CA+CA=23
2CA=23-7
2CA=16
CA=8 SO,
BC=7+8=15 NOW WE CAN FIND ANS
AB=√CA^+BC^
AB=√64+225
AB=√289=17
tan B=BC/AC
15/8 AND
SIN A=AC/AB
=8/17 ANS|
BC-CA=7
THEN,
BC=7+CA
PUT IN IST EQUATION
7+CA+CA=23

AB=√64+225
AB=√289=17
tan B=BC/AC
15/8 AND
SIN A=AC/AB
=8/17 ANS|
