Question

How find th missing hight

Answer 1

1 5/7 yards

Explanation:

The 2 triangles are similar so the corresponding sides ( including the height) will be in the same proportion, so:-

7/4 = 3/x

7x = 12

x = 1 5/7

So the height will be 1 5/7

Answer 2

base = 4 yards, height = 1 5/7 yards

Explanation:

The scale factor relating the dimensions of the smaller triangle to the larger is 4/7, the ratio of the lengths of their bases. That same scale factor applies to the height, so the smaller height is ...

... (3 yards) × (4/7) = 12/7 yards = 1 5/7 yards
