The scale factor of triangle DEF to triangle HJK is 5/2. If EF =15 find JK
EF : JK = 5 : 2
15 : JK = 5 : 2
15 * 2 = JK * 5
30 = 5(JK)
5(JK) / 5 = 30 / 5
JK = 6
Am I CORRECT ON THIS ONE?
Looks like EF and JK are corresponding sides of similar triangles. Each side of DEF is 2.5 times larger than the corresponding side of HJK. Therefore JK = EF/2.5 = 15/2.5 = 6.
You are correct
THANKS
