Find x and the lengths of both PQ and PR given that SQ is a median of APRS, PR = 8х — 39, and QR = 4х 17.
To find the value of x and the lengths of both PQ and PR, we can use the properties of medians in a triangle.
In triangle APRS, SQ is a median, which means it divides the side PR into two equal parts. So, we have:
PR = PQ + QR
Given:
PR = 8x - 39
QR = 4x + 17
Now, we can use these equations to find x and the lengths of PQ and PR:
8x - 39 = PQ + (4x + 17)
Now, combine like terms:
8x - 39 = PQ + 4x + 17
Next, move the 4x and 17 to the left side of the equation:
8x - 4x - 39 - 17 = PQ
Simplify further:
4x - 56 = PQ
Now, you have the length of PQ in terms of x. To find the value of x, you may need more information, like the length of SQ or another equation.
If you have additional information or constraints, please provide them so I can help you find the value of x and the lengths of PQ and PR.
