Answer:
The 3rd option is correct ♡
a) 5 m
b) 8 yd
Step-by-step explanation:
a) Take the ratios of the legs of the triangles. Since they are similar triangles, those ratios are equal.
d/(4 m) = (10m)/(8 m)
Solving for d,
d =(10/8)(4 m) = 5 m
b) m/(10 yd) = (12 yd)/(10 yd + 5 yd) = 12/15 = 4/5
Solving for m,
m = (4/5)(10 yd)
= 8 yd
