Answer:
17) 53.2
18) 17
Step-by-step explanation:
In similar triangles theorem, the ratio of the corresponding sides of two triangles are equal.
17) To determine x, ratio of the sides of 1st triangle/Ratio of the sides of 2nd triangle.
Ratio of base to the missing side:
7.6/x = 13.6/95.2
7.6/x = 13.6/95.2
7.6/x = 0.1428
7.6= 0.1429x
x = 53.2
18) ratio of shortest side/ longest side
3.4/7.9 = x/39.5
x = 3.4/7.9 × 39.5
x = 17
