Answer:
[tex]{\mathrm{view \: explanation}}[/tex]
Step-by-step explanation:
[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]
[tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex]
[tex]tan \theta = \frac{opposite }{adjacent }[/tex]
[tex]sinX=\frac{21}{35}[/tex]
[tex]tanX=\frac{21}{20}[/tex]
[tex]sinC=\frac{30}{50}[/tex]
[tex]cosC=\frac{40}{50}[/tex]
