Answer:
false.
Step-by-step explanation:
Factors for 21: 1, 3, 7, and 21. Factors for 22: 1, 2, 11, and 22.
Answer:
XY = 18
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
10 XY = 180 ( divide both sides by 10 )
XY = 18
