Question

The triangles are similar, find the length of the unknown side. Round your answers to the nearest tenth (0.1), if necessary.

Answer 1

Answer:

$22$

Step-by-step explanation:

Similar shapes must have corresponding sides in a constant proportion. Therefore, we can set up the following equation and solve for $?$:

$\frac{28}{42}=\frac{?}{33}$ (divide corresponding sides)

$\frac{28}{42}=\frac{?}{33},\\\\?=\frac{28\cdot 33}{42}=\boxed{22}$
