n = 24

Explanation:

These triangles are mathematically similar

# n = 12/5 * 10 #

# n = 24 #

#n=24#

Explanation:

The triangles are similar so their sides are in the same ratio.

#(AB)/(AC) = (QR)/(QS)#

#5/10 = 12/n#

By observation we can see that the denominators are double the numerators, giving #n = 24#

However if we solve for #n# by cross-multiplying we get:

#n = (10xx12)/5#

#n = 24#
