Answer: 15
Step-by-step explanation: Use the formula: 
Remember 
should always be the hypotenuse or the longest side.
---> evaluate the exponents
----> subtract 12544 to the other side
---> take the square root of both sides
I would say 25 is the answer to it
1 + tan ² Ф=sec²Ф
1+(12/5)²=sec²Ф
169/25=sec² Ф
sec Ф=⁺₋√(169/25)=⁺₋13/5
sec Ф=1/cos Ф ⇒cosФ=1/sec Ф
cos Ф>0 ⇔ sec Ф>0 ⇔ sec Ф=+ 13/5
cos Ф=1/secФ
cos Ф=1 / 13/5=5/13
we can calculate the sin Ф, with this method.
sin²Ф + cos²Ф=1 ⇒ sin Ф=⁺₋√(1-cos² Ф)
sin Ф=⁺₋√[1-(5/13)²]=⁺₋12/13
like cos Ф>0 and tan Ф>0 ⇒ sin Ф>0 ⇒sin Ф=12/13
answer: d.12/13
other method
tan Ф=sin Ф / cos Ф
12/5=sin Ф / 5/13
sin Ф=(12/5)*(5/13)=12/13
answer: d.12/13

Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
Step-by-step explanation:
Hi, to answer this question we have to analyze the equation given:
3.00 + 0.50 m = 9.50
Where m is the number of miles.
The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.
So, the correct statements are:
- The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
- Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
