Both Jo and Liam are correct
Explanations:From Jo's equation:
sin 40°=BC 62
Note: sin 40° = 0.64
0.64 = 62 BC
To find BC, divide both sides by 62
[tex]\begin{gathered} \frac{0.64}{62}=\text{ }\frac{62\text{ BC}}{62} \\ 0.01\text{ = BC} \\ BC=0.01\text{ } \end{gathered}[/tex]From Liam's equation:
cos 50°=BC62
Note: cos 50° = 0.64
0.64 = 62 BC
To find BC, divide both sides by 62
[tex]\begin{gathered} \frac{0.64}{62}=\text{ }\frac{62\text{ BC}}{62} \\ BC\text{ = 0.01} \end{gathered}[/tex]Both Jo and Liam are correct because when both equations are used, the same value of BC is gotten.
