Answer:
(6)=120°
(10)=72°
(20)=36°
Step-by-step explanation:
(n-2)×180°
(6-2)×180°=720°
6÷720°=120°
10÷720°=72°
20÷720°=36°
Answer:1375
Step-by-step explanation:
X= 15 is given
X squared is 15x15 = 225
1600 - 225= 1375
Step-by-step explanation:
if they are parralel it means gradient is the same
finding equation we find another point which is (x,y)
therefore y - 2/ x - 4 should be equal to 2/3.
y - 2 = 2/3(x - 4)
y - 2 = 2/3x - 8/3
y = 2/3x - 8/3 + 2
Horizontal
As they have the same y coordinates
