\text{Answer: }\angle 5=31\textdegree

Explanation:

Since we have given that

AB║CD

and

m\angle 2=31\textdegree

Since we know that AB║CD

So, Alternate angles will be equal to each other and

\angle2=\angle 5\\\angle 1=\angle 6

So, value of angle 2 is equal to value of angle 5 i.e.

\angle5=\angle 2=31\textdegree

Hence ,

\angle 5=31\textdegree

△ABC is similar to △XYZ. Also, side AB measures 6 cm, side BC measures 18 cm, and side XY measures 12 cm.
Serggg [28]

Answer:

value of sides YZ is 36 cm

Step-by-step explanation:

Similar triangles states that the length of the corresponding sides are in proportion.

Given that: ΔABC is similar to ΔXYZ

then;

Corresponding sides are in proportion i.e

\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}    .....[1]

As per the statement:

side AB = 6 cm, side BC =18 cm and side XY = 12 cm.

Substitute these in [1] to solve for side YZ;

\frac{6}{12}= \frac{18}{YZ}

or

\frac{1}{2} = \frac{18}{YZ}

By cross multiply we have;

YZ = 36 cm

Therefore, the value of sides YZ is 36 cm
