Step-by-step explanation:
Answer:
Think simple.
We already have parallelogram LENS, therefore:
∠L ≅ ∠ENS
We also have parallelogram NGTH, therefore:
∠T ≅ ∠GNH
Finally, we can also see that:
∠ENS ≅ ∠GNH (opposite angles)
=> ∠L ≅ ∠T
Answer:
45 people prefered coffee, 81 people prefered tea. A total of 126 people were surveyed.
Step-by-step explanation:
Let t be the people who prefer tea, and let c be the people who prefer coffee.
The ratio between tea and coffee is 9:5, thus we have t/c=9/5. Cross products give us 5t=9c.
Also, we have 36 more people prefer tea than coffee, so we have c+36=t
Thus we have: 5(c+36)=9c
5c+180=9c
180=4c
c=45
c+36=t
45+36=81
So the error is 1 mile
I ask what % of 15.5 = 1
How you write this;
x/100 *15.5 = 1
15.5x = 100
x = 100/15.5
x = 6.451629 round up 6.45
% error is 6.45 %
