Question

Triangle JKL is similar to triangle MNO. Find the measure of side NO. Round your

answer to the nearest tenth if necessary.
O
11
K
15
M
58.8

Answer 1

43.1

Explanation:

Similar shapes have sides of the same proportions. This means that one shape is just an enlargement of the other.

In this case, triangle MNO is an enlargement of triangle JKL so we can work out a scale factor.

To work out the scale factor, we can do 58.8 ÷ 15 = 3.92. To find side NO, all we have to do is multiply 11 by 3.92 to get 43.12 ≈ 43.1 (rounded to the nearest tenth).

Hope this helps!
