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
The total cost of items Gina bought on her shopping trip given the percentage discount is $26.31
Given:
<em>cost of two books</em> = $4.99 + $12.99
= $17.98
<em>Amount paid for books</em> = $17.98 - 10% of $17.98
= 17.98 - 0.1 × 17.98
= 17.98 - 1.798
= $16.182
<em>Cost of notebooks = quantity × price</em>
= 2 × $2.88
= $5.76
<em>cost of composition books = quantity × price</em>
= 3 × $0.79
= $2.37
<em>cost of pencil packs</em> = quantity × price
= 2 × $1.89
= $3.78
Total cost = $5.76 + $2.37 + $3.78
= $11.91
<em>Amount paid for school supplies </em>= $11.91 - 15% of $11.91
= 11.91 - 0.15 × 11.91
= 11.91 - 1.7865
= $10.1235
Therefore,
total cost of all items Gina bought = $16.182 + $10.1235
= $26.3055
Approximately, $26.31

Step-by-step explanation:
If m is parallel to n and one of its angle is 25
Therefore, the vertically opposite angle to angle of 25 is also equal to 25
Now, we have to find x
Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)
Therefore, x =155
