the picture in the attached figure
we know that
in the right triangle FON
sin F=opposite side angle F/hypotenuse
in this problem
opposite side angle F=ON--------> 9 units
Hypotenuse=FN--------> 18 units
so
sin F=ON /FN-------> sin F=9 /18
therefore
the answer is the option
B.) sin F 9/18
The quotient is : 5x-12+(25)/(x+3)
The remainder is : 25
Answer:
81
Step-by-step explanation:
subtract 3 from both sides->x^1/4=-3
set both sides to the power of 4-> x=(-3)^4
solve-> x=81
<u>Short answer</u> = C) 8/10
<u>Working :</u>
Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units
Adjacent = 6 units
Hypotenuse = 
= 
= 
= 10 units
Cos B = Adjacent/ Hypotenuse
∴ cos B= 8/10
6/8 can be simplified to 3/4. Therefore the answer is C. 20 X 3/4
