Atrain going into houston has 218 passengers. a train going ou has t of 129 passengers give me an estimate for the total number of passengers on the two trains

An estimted 350 passengers.

Step-by-step explanation:

Let's estimate this sum:  replacing 218 with 220 and 129 with 130, we have the simpler addition problem 220+130, which works out to 350 passengers (total on the two trains).

101.08 degrees to nearest hundredth.

Step-by-step explanation:

Use the Cosine Rule:-

25.7^2 = 10.7^2 + 21.4^2 - 2*10.7*21.4 * cos x   where x is the required angle.

cos x =     (25.7^2 - 10.7^2 - 21.4^2) / (-2*10.7*21,4)

=  88.04 / - 457.96

= -0.192244

x = 101.08 degrees
