Answer: arc ef is 68
Step-by-step explanation:
Since EF and FG are the same length (given)
and DE and DG are the same length (both are radius of the circle)
and DF is a shared side, the 2 inscribed triangles are congruent, making angle EDF also 68
The measure of an arc is the same as the measure of the angle across from it

Answer:
B
Step-by-step explanation:
PEMDAS
8 + 2^3 x 5
8 + 8 x 5
8 + 40
48
We are given 2 sides 18.7, 16.1 and a NON-included angle.
We have to calculate the altitude of the triangle.
altitude = 18.7 * sine (35)
altitude = 18.7 * 0.57358
altitude =

10.725946

In this case, side c is greater than the altitude and is less than side a so 2 two triangles will be formed.
