His flight covered about 3610 miles in 33.5 hours. find the unit rate in miles per hour

3610 ÷ 33.5 = 107.761194 107.76 miles per hour

The sum of each of the angles in a triangle always equals 180. We are given angles A and C so all we need to do is add them together and subtract from 180 to find the missing angle.

Angle C is 34
Angle A is 90 (that little box indicates 90)
34+90=124
180-124=56

Ange B is 56 degrees.

Hope this helps!!
