Given triangle ABC, which equation could be used to find the measure of ∠B? right triangle ABC with AB measuring 6, AC measuring 3, and BC measuring 3 square root of 5 cos m∠B = 2 square root of 5 all over 5 sin m∠B = square root 5 cos m∠B = square root of 5 over 2 sin m∠B = 2 square root of 5 all over 5

is the correct answer.

Step-by-step explanation:

We are given a right angled with the side measurements as:

AB = 6

AC = 3

BC = 3

In a right angled triangle, the angle of is the largest angle and the side opposite to the right angle is the largest.

We are given that the side BC = 3 which has a value greater than 6 which means side BC is the largest side.

And angle opposite to BC is is the largest i.e.

Please refer to the attached image for the given dimensions of the triangle.

Now, we can apply trigonometric rules to easily find out the value of

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
