Answer 1

Answer:
`z=91.6`

Step-by-step explanation:

A pentagon has 5 sides and 5 angles and equals up to 540 degrees

So we need to make the equation of

`145+120.1+112.3+71+z=540`

`448.4+z=540`

`448.4+z=540\\-448.4 = -448.4`

`z=91.6`c

To check work just plug in 91.6 for z in the equation that was created
`145+120.1+112.3+71+91.6=540`
