Question

These two scalene triangles are similar with a scale of 7:4 what is true about these figures

Answer 1

we know that

$scale\ factor =\frac{7}{4}$

if triangle GHJ and triangle MKN are similar

then

$\frac{GH}{MK} =\frac{HJ}{KN}= \frac{GJ}{MN} = \frac{7}{4}$

m∠g°=m∠m°

m∠h°=m∠k°

m∠j°=m∠n°

therefore

the answer is

$\frac{GJ}{MN} = \frac{7}{4}$

Answer 2

The answer would be GJ/MN=7/4 because the others don't work.
