Answer:
WV = 42
Step-by-step explanation:
Δ UVW and Δ XYW are similar ( by the AA postulate ) , then the ratios of corresponding sides are in proportion, that is
=
( substitute values )
=
( cross- multiply )
15 WV = 630 ( divide both sides by 15 )
WV = 42
Answer:
27
Step-by-step explanation:
Let the number to find out be 'x'
Therefore,
according to the condition given question, we get the equation as
Now,
squaring both the sides, we get
2x - 5 = 49
on adding 5 both sides, we get
2x - 5 + 5 = 49 + 5
or
2x = 54
or
x =
or
x = 27
Hence, the number is 27
