Answer:
0 < x < 28
Step-by-step explanation:
If a triangle has 2 sides, with lengths 7 and 21, the third side must -
have a length longer than zero <u>and </u>less than (7+21) = 28
so if the 3rd side has length x, then
0 < x < 28
Answer:
x = -17
Step-by-step explanation:
3x-7=4+6+4x
Combine like terms
3x-7 = 10+4x
Subtract 3x from each side
3x-3x -7 =10+4x-3x
-7 = 10+x
Subtract 10 from each side
-7 -10 = 10+x-10
-17 =x

thanks ?
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
