the angle is greater than 180 degrees so it makes it an obtuse triangle
Answer:
Step-by-step explanation:
So Blakes sleep 8 hours per night during the school day
8 hours/night...................................100%
6.5 hours/night...................................?
6.5*100/8=81.25
the change in percentage is 100-81.25=18.75%
the percentage change is 18.75
if it is easier for you, another method is:
8-6.5=1.5 subtract the original amount to the new amount
1.5/8=0.1875 divide by the original amount
0.1875*100=18.75 find the percentage
Answer:
should be 27
Step-by-step explanation:
60% of 180 is 108
25% of 108 is 27
Perimeter= 2 ( length + width)
2×(12+6)
2×18
=36
