Question

ln the isoscles trapezim PQRS , PR=(5X+2)cm and QS=(8X-7)cm.find the length of PR

Answer 1

hey mate here is your answer...
as we know that two sides of an isosceles triangle is equal .
so ,PR= QS
so we equate there value.
5x+2=8x-7
2+7=8x-5x
9=3x
3x=9
X=3
PR= 5x+2
5*3+2=PR
PR=17
so the value of PR is 17 cm..
hope it may help you..
