H − 1 − 7 − g − 1 for g = 1 and h = 12.

2

Step-by-step explanation:

You just need to put in the values of g and h into the equation.

h − 1 − 7 − g − 1 = 12 - 1 - 7 - 1 - 1

                         = 12 - 10

                         = 2

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
