Explanation:
1.angels on a straight line add up to 180degrees
2.when you see the signs at number 6 and 7 it means it is 90 degrees
EG. number 6.it will be 90degrees+29degrees=119degrees remember that all angles on a straight line add up to 180 degrees. to get angel xwy you will subtract 119 degrees from 180 degrees =xwy which is 61 degrees
Answer:
a=16
Step-by-step explanation:
We have that
A(-4,-4) B(-2,5) C(2,1) D(2,-4)
step 1
find the distance AC with the formula
d=√[(y2-y1)²+(x2-x1)²]------> dAC=√[(1+4)²+(2+4)²]----> dAC=√61 units
dAC=√61-----> dAC=7.8 units
the answer is
the option
<span>B. 7.8 units</span>

Our water faucet leaked 3 2/6 liters of water every 3/5 of a hour.
We are to find the rate in liter per hour at which the water faucet leaked.
First, use the number of liters the water faucet leaked in 3/5 of a hour.
This is 3 2/6 = 20/6
Therefore, the number of liters of water faucet leaked in 1 hour is
(20/6) / (3/5)
Before we solve this, we should simplify,
20/6 can be simplified to 10/3
3/5 cannot be simplified
Then, we should modify our problem to use reciprocation instead of a complex fraction,
(10 • 5) / (3 • 3)
This equals 50/9
Now, solve 50/9 for 5.555555555556
This rounds to 5.6
Thus, the required rate at which the water faucet leaked is 5.6 liters per hour.
