A boat traveling with a velocity measured in meters per second is described by the vector b⇀=⟨−2,−5⟩. In two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. Include all of your calculations in your final answer.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

c.

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
