Answer:

A= 23.2

Step-by-step explanation:

a^2=b^2+c^2-2bc CosA

a^2=11^2+19^2-2(11)(19)Cos 98

a^2=121+361-418cos98

a^2=121+361-(-58.17)

\sqrt{a^2} =\sqrt{540.17}

a=23.2

-----------

hope it helps..

have a great day!!

A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. On the return trip, the bird travels 3 miles per hour
Darya [45]

Answer:

Step-by-step explanation:

Let y represent the distance travelled downwind by the bird from its nest.

Distance = speed × time

A bird leaves its nest and travels 18 miles per hour downwind for 2 hours. Distance covered in travelling downwind is

2 × 18 = 36 miles

On the return trip, the bird travels 3 miles per hour slower and has 5 miles left after 3 hours. It means that the speed at which the bird travelled is 18 - 3 = 15 mph. Also, the distance covered in 3 hours is 36 - 5 = 31 miles. Therefore,

a) distance of the entire trip is

36 + 36 = 72 miles

b) time spent in travelling downwind from its nest is 2 hours

Time for the return part is

3 hours + 5/15 = 3 + 1/3 × 60 minutes

= 3 hours 20 minutes

Total time for the trip is

2 hours + 3 hours 20 minutes

= 5 hours 20 minutes 0 seconds

The fifth term of an arithmetic sequence is 23 and the 12th term is 72? Determine the first three terms of the sequence and the
Arisa [49]

Answer:

the first term is a1

the distance between the numbers is d

we have:

a5 = a1 + 4d = 23

a12 = a1 + 11d = 72

so we have the equation:

a1 + 4d = 23

a1 + 11d = 72

=> a1 = -5

d = 7

=> an = -5 + 7(n - 1) = 7n - 12

with an = 7n - 12

=> a2 = 2

a3 = 9

so the first three terms is -5; 2; 9
