Help. Find the value of x to the nearest tenth
1 answer:
I will assume that line 4 bisect line x exactly in half. This means that if we solve the last side of the triangle like seen in the pic below we will know what half of line x is
To find the length of the last side of the triangle (let's call this y) you must use Pythagorean theorem
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = 4
b = y
c = 6
^^^Plug these numbers/variables into the theorem
solve for y
16 + = 36
= 20
x = √20
x ≈ 4.472
^^^This is only half of x so if you double it then it will get you the full length of x
4.472 * 2 = 8.944
8.9 (D)

Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.
Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.
Indeed, those two numbers are relatively prime.

so our slope is undefined, that means a vertical line, check the picture below
