Question

Work out xz and qr need asap​

Answer 1

Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal

(a)

$\frac{xPR}{XZ}$ = $\frac{PQ}{XY}$ , substitute values

$\frac{6.5}{XZ}$ = $\frac{7.2}{18}$ ( cross- multiply )

7.2XZ = 117 ( divide both sides by 7.2 )

XZ = 16.25 cm

---------------------------------------

(b)

$\frac{QR}{YZ}$ = $\frac{PQ}{XY}$ , substitute values

$\frac{QR}{17}$ = $\frac{7.2}{18}$ ( cross- multiply )

18QR = 122.4 ( divide both sides by 18 )

QR = 6.8 cm
