Question

d) IF ABCD is a parallelogram then find the length of its diagonals.​

Answer 1

Step-by-step explanation:

3b+2=5b-12 2a+8=8a-16

3b-5b= -12-2 2a- 8a= -16-8

-2b= -14 -6a= - 24

b= 7 a=4

so 3(7)+2=23 2(4) +8= 16

5(7)-12= 13 8(4) -16 = 16

so the length of diagonal BD is 23+13= 36

& the length of diagonal AC is 16+16= 32
