The perimeter of a triangle can be found by adding up all the sides
so the perimeter is :
5 + 8 + x =
13 + x <==
lol i cant answer that im only in middle schoolStep-by-step explanation:
Consider ∆JWZ and ∆JKZ
WZ~KJ (given)
<u>/</u><u> </u><u>WZJ</u>~<u>/</u><u> </u>KJZ (given)
JZ~JZ (common)
Therefore,
∆JWZ~∆JKZ by SAS congruence rule.
JW~ZK by CPCT.
So yuo simplyfly
15:20=3:4
6:8=3:4
8:12=2:3
9:12=3:4
so your answer is not c
