According to google, the red marks mean those two lines are the same length. If that's the case, we know that x is the angle in both corners of the lower triangle. We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40. That leaves 140 for the rest. Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees. It is divided in two parts, the lower one of which we just found to be 20. So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees
Answer:
93/100
Step-by-step explanation:
T=[log(6000/2925.9)/log(1+0.039/2)]/2
T=18.6 years
18 years and 6 months

Answer:
66 km
Step-by-step explanation:
Given that
Number of km's traveled by a car using g liters of gasoline = 12g
Number of gallons of gas required to travel 12g kilometers = g
We have to find
How far this car can travel using 
or 5.5 liters of gasoline = x= ?
Now we can find this by substituting g= in the the above equation representing number of kilometers traveled by the car.
Number of km's traveled by a car using liters of gasoline = 12 ()
x = 12 (5.5)
x= 66 km
So, the car travels 66km in 5.5 liters of gasoline
Answer:
-2/radical 3
Step-by-step explanation:
radical 8 can be written as 2 times radical 2
radical 6 can be written as radical 2 *radical 3
you have radical 2 as common for both so you can cancel those
and you remain with -2 on the top and radical 3 on the bottom
so the answer is -2/radical 3
