There are 221 students on a filed trip. five of the students ride in a van. the rest of the students fill 6 buses. enter an equation that can be solved to find the number of students, s, that are on each bus

Step-by-step explanation:

Let s be the number of students in each of 6 buses. Then there are 6s students in all buses.

Five of the students ride in a van. In total, in a van and in buses there are   students.

There are 221 students on a filed trip. So,

The measure of angle D is 39 degrees.

Since it’s an isosceles triangle, the two unmarked angles are equal. Since you know there are 180° in a triangle, subtract 102° from 180° to get 78°. Then, cut that in half since you need to divide it equally among the two remaining angles.
