need measurements for
A
OAR
DAR

Answer 1

a = 12, <ONS = 68 , <OAB = 68

Explanation:

Since they are in a parallelogram that means that some of these angles equal each other or are the same.

<ONS = <OAB

(4a + 20)° = (80 - a)°

5a = 60

a = 12

Plug an into the to get angles.

<ONS = 4a+20

<ONS = 4*12+20

<ONS = 48+20

<ONS = 68

<OAB= 80-a

<OAB = 80-12

<OAB = 68
