The measure of PR from the diagram given is 40
The given diagram is an isosceles triangle, For an isosceles triangle, two of sides and angles are equal. hence;
PR = QR
5n = 32 + n
Collect the like terms;
5n - n = 32
4n = 32
n = 32/4
n = 8
Get the measure of PR;
PR = 5n
PR = 5(8)
PR = 40
Hence the measure of PR from the diagram given is 40
