Answer:
=21k-18
Step-by-step explanation:
The answer is C, 18 buses.
60 minutes = 1 hour. 60 divided by 10 = 6. 6 x 3 = 18.
The sum of the measures of the angles of a triangle is 180 deg.
m<J + m<K + m<L = 180
72 + 36 + m<L = 180
m<L = 72
Both angles J and L measure 72 deg.
Angles J and L are base angles measuring 72 deg.
Angle K is the vertex angle measuring 36 deg.
