First find the value or (DEA)
For this you will have to use the Pythagorean theory,

C is mainly the hypotenuse,
Meaning you either want to find A or B,
Since the hypotenuse has two segments, both values are 10, then just add them together making it 20,
Then 16 will be A or B, in this case it will be A,
To find a you must first move A to the other side by doing the opposite,

Now plug in the values,



Now just find the square root of both factors,

The value of (DEA) is,

Now we want to find (d)
Since 12 is the value of the base, then divide it 2 to find (DE), after just repeat the whole process but with the value of hypotenuse 10 instead of 20 since we want to find the smaller triangle,

Now plug in the value



Now find the square root of both factors,


The value of (d) is (8)

Make it a improper fraction first.
11/6 * 2 = 22/6
Which is 3 2/3
Answer:
-23
Step-by-step explanation:
As I increases by 18, y decreases by 12. From the last value in the table, I needs to increase by 2·18 for it to become zero. Hence the y-intercept will be 2·12 less than the last value in the table:
1 - 2·12 = -23 . . . the y-intercept
Tony's current scores are 22 and 25.
Let x = Tony's next score.
To make the lower required score of 27,
(x + 22 + 25)/3 = 27
x = 81 - 47 = 34
To make the upper required score of 32,
(x + 22 + 25)/3 = 32
x = 96 - 47 = 49
Answer:
Tony should score between 34 and 49
