C. 1.5 hours. divide 12 by 8, and you get 1.5.
1. You have the following information:
Sinx=5/13
Cosx=12/13
2. By definiton, you have:
Tanx=(Senx)/(Cosx)
3. When you susbtitute Senx=5/13 and Cosx=12/13 into Tanx=(Senx)/(Cosx), you obtain:
Tanx=(Senx)/(Cosx)
Tanx=(5/13)/(12/13)
Tanx=(5)(13)/(13)(12)
Tanx=65/156
4. Therefore, the answer is;
Tanx=65/156
You put the point at (5,0) since it’s rise over run you move 3 up n go 4 to the right
Assuming the ':' means an = sign, 2
=10 simplifies to 2
=8
