Answer:

35 cm

Step-by-step explanation:

You can use the Cosine Rule to find the length of a side when two sides and the included angle are given.

a² = b² + c² - 2bc cos A

a² = (36²) + (52²) - 2(36)(52) cos 42°

a² = (1296) + (2704) - (3744)(0.7431448255)

a² = (4000) - (2782)

a² = 1218

a = ✓1218

a = 34.9 cm

Find the measure of side XY.
Ymorist [56]

Answer:

XY = 18

Step-by-step explanation:

The figures are similar so the ratios of corresponding sides are equal, that is

\frac{XY}{BC} = \frac{YZ}{CD} , substitute values

\frac{XY}{12} = \frac{15}{10} ( cross- multiply )

10 XY = 180 ( divide both sides by 10 )

XY = 18
