From secant theorem, 16^2 = 8(12 + y); where y is the missing length of the secant.
256 = 8(12 + y)
12 + y = 32
y = 32 - 12 = 20
From chord theorem, 4x = 4(20)
x = 20
To the left of the decimal point needs to be somewhere between 1 and 9 (one place). 983 in scientific notation would be 9.83 x 10^2. Do you understand how i got that? I got the 10^2 because i am moving the decimal point over two places to the left. If i move the decimal point to the right, then the exponent would be negative. Example:
0.00983 in scientific notation would be 9.83 x 10^-3 because i moved the decimal point three places to the right.
We rewrite it in a more functional form:
I'll make a vertical table, easier to type. For each x we subtract 3 to get y.
x y
0 -3
1 -2
2 -1
3 0
Answer:
identify if the angle is a right angle, if it is bisected it means both sides are the same, set both equations equal to each other or add them up and set them equal to 90 or 180
Step-by-step explanation:
that is the explanation.
You have to start by adding 4/5 in order to get x alone. When you add 4/5 and 6/13, you have to find the smallest number that both the fractions can have as the same number in the denominator. For this case it is 5 because 13 times two, three, or four won't equal a number that 5 times any whole number can equal. 13 times 5 is 65 and 6 times 5 is 30 so our new fraction is 30/65. For 4/5 we do the same. In order for the bottom number to equal 65, you have to multiple the fraction by 13. 5 times 13 is 65 and 4 times 13 is 52 so our new fraction is 52/65. We now add 52/65 and 30/65 to get 82/65!
