ΔART ~ ΔEFG<br><br><br><br> Find m.<br><br> 3 1/3<br> 7 1/2<br> 1<br> 19 1/5

Vinil7 [7]

Answer:

m = 3 1/3

Step-by-step explanation:

since the triangles are similar then ΔATR must be isosceles also

we can set up this proportion:

AR/TR = EF/EG

12/8 = 5/m

cross-multiply to get:

12m = 40

m = 40/12 or 20/6 which is 3 1/3
