Question

The angles of a pentagon are in the ratio 2:4:2:1:1. If the total measure of the angles of a pentagon is 540 degrees, what are the measures of each angle?

(Please answer with working/show working)

Answer 1

Answer:

54

Step-by-step explanation:

2x+. 4x.+ 2x. + 1x.+ 1x.= 540

10x.=540

X=540/10

X=54

Answer 2

Answer:

let the common angle be x

2x+4x+2x+x+x=540

10x=540

x=54

therefore each angle will be

2x=108

4x=216

2x=108

x =54

x =54
