The total amount would be 13/20 I believe I'm not too sure
Answer:
23+ .5 + .06
20+3+.56
10+10+ 3.56
Step-by-step explanation:
If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
