5 Read what Alicia says.

The angles of this pentagon are 100°, 105°, 72°, 126° and 127°.
Explain why she must be wrong.​

Answer 1

all the angles of the pentagon do not add up to 540

Explanation:

total degree in a shape

180 × (n-2) where n is the number of side

a pentagon has 5 sides so

180 × (5-2)

= 540

100+105+72+126+127= 530

all the angles of the pentagon do not add up to 540
