4(-1)-2 = -4-2 = -6 i hope this help
Answer:
<u>Same side angles are supplementary</u>
L+k=180
18x-18+72=180
18x=126
x=7
m∠18(7)-18
= 108°
---------------------
hope it helps...
have a grat day
360°/60 = 6
25 x 6 = 150°
18 x 6 = 108°
15 x 6 = 90°
2 x 6 = 12°
then draw a pi chart with these angles
hope this helps! please mark branliest?
