Answer:
54°
Step-by-step explanation:
Since the 5 vertex angles are congruent, each vertex angle = 360/5 = 72°
The sum of the angles of each triangle is 180-72 = 108°
The base angles of each triangle are equal to each other so each base angle = 108/2 = 54°
The answer is M = -2
D) -2
<u>94</u>
Equating the mean to the scores :
m<C = 180 - (90+32)
= 180 - 122
= 58°
