Break it down it’s a lot easier
Answer:
think it is d
Step-by-step explanation:
<span>Second angle = x
First angle = 2x
Third angle = x + 68
x + 2x + (x + 68) = 180
4x + 68 = 180
4x = 112
x = 28.
First angle = 56 degrees
Second angle = 28 degrees
Third angle = 96 degrees
Total = 180 degrees.</span>
Answer:
<h2>0.75(3/4) part of the room</h2>
Step-by-step explanation:
Step one:
given data
we can express the given data mathematically as
John can paint 0.5room in 2/3 hours
let the part of the room he can paint in an hour be x
so
if he takes 2/3 hours to paint 0.5 room
then he will take 1 hour to paint x
cross multiply we have
x= 0.5/2/3
x=0.5*3/2
x= 1.5/2
x=0.75 part of the room
75/100= 15/20=3/4 part
