A 60-yard long drawbridge has one end at ground level. The other end is initially at an incline of 5°.

During one stage of the drawbridge’s motion, the raised end is 18 yards above the ground. What is the incline of the drawbridge to the nearest hundredth?

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
