Answer:

Step-by-step explanation:

funny i had the exact same queston like this anyways

pentagon=5 sides

5-2=3

3*180

540

add all them together

104+118+96+115=433

540-433

107

since a line equals 180

180-107=

73

Answer 2

Answer:

D    73º

Step-by-step explanation:

Total angles

a = (sides - 2) * 180

a = (5 - 2) * 180

a = 540

-------------------

Missing angle

x = 540 - (104 + 118 + 96 + 115)

x = 107

a is supplementary to x

m∠A = 180 - 107

m∠A = 73º
