In exercises 25-32, use the appropriate arc length to find the missing information s = arc length (in radians)
r = radius
\theta = central angle in radians
s r ∅
25 ? 2in 25 rad
26 ? 1cm 70 rad
27 1.5ft ? π/4 rad
28 2.5cm ? π/3 rad
29 3m 1m ?
30 4in 7in ?
31 40cm ? 20°
32 ? 5ft 18°

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
