Answer:
x = 111°
Step-by-step explanation:
x + 120+158+126+125+121+139= 900°
x + 789 = 900
x = 900 - 789
x = 111
111
The sum for a 7-sided interior polygon is 900
126+158+120+125+121+139=789
900-789=111
the answer is x=-2 as answer
The answer is B if the octagon has side lengths of 8
12 feet
Given: length = 15 feet, width = L x 80%
Unknown: width = ?
width = L x 80%
w = (15ft) x 80% or (15ft) x .80
w = 12 ft
