Answer: The tan 130° is expressed as 
Step-by-step explanation:
Since we have given that

As we know that
cos (π - θ ) = -cos θ
so, cos(180-50)=-cos 130° = -a
so, sin 130° would become

So, tan 130° is given by

Hence, the tan 130° is expressed as 
Answer:
7500
Step-by-step explanation:
5,000,000÷10,000=500
500×15=7500
