Answer:
Picture #1
Triangles ΔJKL and ΔXYZ have:
∠X is corresponding to ∠J, since they are different (90° vs 38°), the triangles can't be similar
Picture #2
Perimeter is the sum of the sides each has same ratio.
The ratio of the perimeters will be same as the ratio of each corresponding pair.
Correct choice is C. 3:5
Picture #3
Use ratios of corresponding sides:
- ST/PQ = TR/RP
- ST / 28 = 105 / 30
- ST = 28*105/30 = 98 m
Correct choice is B
