First you have to put the numbers in numerical order: 2,5,9,10,12,20,20,60
Because they are even number, look for the 2 numbers in the middle: 10,20
Add the number: 10 + 20 = 30
Divide by 2: 30÷2
= 15
Answer:
the ladder is 60 feet and the angle is 75 degrees guess and check sin75=x/60
0.9659258263=x/60
57.9555=x
57.96=x
so B
9514 1404 393
Explanation:
Your different answers came about as a result of an error you made in the Pythagorean theorem calculation.
√(100 +100) = √200 = 14.142 . . . . same as vector calculation
Answer:
The difference is 1
Step-by-step explanation:
we know that
The difference is equal to subtract the number -5/9 from 4/9
so
Start by simplifying the right side:
3m + 12= 2m + (20-2)
3m + 12= 2m + 18
Now get m’s on to one side:
3m + 12= 2m + 18
-2m -2m (Subtract 2m from both sides)
m + 12 = 18
Now get the constants on to the other side:
m + 12 = 18
-12 -12
So:
m= 18-12
m=6
