Question

HELP GEOMETRY PLEASE

Answer 1

For each of the problems, twice the angle formed by the chords is equal to half the sum of the angles of the arcs.

So, for the first problem, we have $94 \cdot 2 = x+103$, so $x = 188 - 103 = 85$. 

For the second, $102 \cdot 2 = x + 118$, so $x = 204 - 118 = 86$.

For the last problem, $106 \cdot 2 = x + 88$, so $x = 212 - 88 = 124$.
