- The triangle \(A B C\) is such that
- \(A B = 15 \mathrm {~cm}\)
- \(A C = 25 \mathrm {~cm}\)
- angle \(B A C = \theta ^ { \circ }\)
- area triangle \(A B C = 100 \mathrm {~cm} ^ { 2 }\)
- Find the value of \(\sin \theta ^ { \circ }\)
Given that \(\theta > 90\)
find the length of \(B C\), in cm , to 3 significant figures.
