What is the length of approximated to the nearest tenth?
A. 49
B. 32
C. 23
D. 7
Side AB has a length of 7x and Side CB has a length of 9x - 14. It is an equilateral triangle.
So the sides must be the same ....
9x - 14 = 7x
2x =14
x = 7
( I am confused that this confused you)
Lol ya im not a math person
To find the length of side AB, we need to know the value of x. Since the triangle is equilateral, it means all sides are of equal length.
So, we can set up an equation using the given information:
7x = 9x - 14
To solve for x, we'll start by isolating the x terms on one side of the equation:
7x - 9x = -14
-2x = -14
Then, divide both sides by -2:
x = -14 / -2
x = 7
Now that we know the value of x, we can substitute it back into the equation to find the length of side AB:
AB = 7x = 7 * 7 = 49
Therefore, the length of side AB is 49.
So, the answer is A, 49, when rounded to the nearest tenth.
