Answer:
90 degree is my guess please
Tan(30°) = opposite/adjacent ⇒
opposite = adjacent * tan(30°) = 25 * 0.5773 ≈14.4 in ← <span>to the nearest tenth.</span>
Answer:
15 days.
Step-by-step explanation:
46 - 16 = 30.
It falls 2 seconds behind each day so the number of required days
= 30 / 2 = 15.
120
70+50=120
180-120=60
180-60=120
Recall that
d/dx sech(x) = - sech(x) tanh(x)
d/dx tan⁻¹(x) = 1/(1 + x²)
Then by the chain rule,
dy/dx = - sech(x) tanh(x) / (1 + x²)
