First lets make 3 1/8 to a improper fraction
multiply 3 * 8 to 24
add 24 + 1 to 25
lets make 1 7/8 an improper fraction
multiply 1 * 8 to 8
add 8 + 7 to 15
join the denominators together
10/8
simplify 10/8 to 5/4
Now lastly make 5/4 a mixed fraction

Answer: 1 1/4.

Your answer would be 1 2/8 (or 1 1/4):
3 1/8 - 1 7/8
25/8 - 15/8
10/8
1 2/8
You can simplify this further to get 1 1/4. Hope this helps!

If tan theta = 12/5 and cos theta < 0, what is sin theta ?
Talja [164]
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

Mrac [35]
For this case we can model the problem as a rectangle triangle.
 We have:
 Length of the sides of the triangle.
 We want to find:
 Length of the hypotenuse.
 Using the Pythagorean theorem we have:
 d ^ 2 = 2 ^ 2 + 2 ^ 2

 d =  \sqrt{2 ^ 2 + 2 ^ 2} 

d =  \sqrt{4 + 4} 

d =  \sqrt{8} 

d =  2\sqrt{2} 

 Answer:
 
She is:
 
d = 2\sqrt{2}
 miles far from her starting point
