X = 20
This is an isosceles triangle so third angle is also 2x because of symmetry.
Angle sum = 5x + 2x + 2x = 9x = 180 degrees
Let's just make 15 students a group. how many groups are there if there r 135 student? 135/15 = 9 groups.
so if each group have 4 adults just multiply 9 by 4,
therefore there will be 36.adults.
