Angle BDC is given as 38° but not drawn in the figure. Amateurs.
We calculate angle DBC
DBC = 180° - 96° - 38° = 180° - 134°
We won't bother subtracting because we're really after
angle ABD = 180° - DBC = 134°
Now we have a Law of Cosines situation,
AD² = AB² + BD² - 2(AB)(BD) cos ABD
AD = √( 5.8² + 27.3² - 2(5.8)(27.3) cos 134°)
AD ≈ 31.61 m
Answer: 31.6 m
Y= -x^2. That’s the answer
Answer:
1/3 y +5
Step-by-step explanation:
five more than one-third y
1/3 y +5
Given that initial time for jogging is,
After each week the time is increased by
This gives an arithmetic sequence.
To find n such that,
Therefore,
So,
Therefore, 9 weeks before you are up to jogging 70 minutes.
