Answer:
yes it would make a acute triangle
Step-by-step explanation:
((5-2)*180)/5=SPT
SPT=108
360-(108+90)=RPT
RPT=162
((n-2)*180)/n=162
162n=(n-2)*180
.9n=n-2
.1n=2
n=20
X/18 = 12.6
Multiply both sides by 18.
x/18 * 18 = 12.6 * 18
x = 12.6 * 18
x = 226.8
The number is 226.8.
If he uses 1/6 for 1/2 the wall he uses 2x as much for the whole wall. because none of the equations have x2 you can ÷1/2 because multiplying by 2 is the same as dividing by a half.
so the answer is 1/6 ÷ 1/2
