Answer:
1). x = 14
2). y = 2.4 cm
Step-by-step explanation:
In the diagram ΔNPQ ~ ΔNLM and NL = 3,
1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]
(3x + 18)° = 60°
3x = 60 - 18
x = 14
2). Since, both the triangles are similar, corresponding sides will be proportional.
y
y = 2.4 cm
The lines are intersected at point (0, -5). So (0, -5) is the solution.
Answer is the third one
(0,-5 )
For one to one function each element in the domain is mapped on to an one and only one element in the co-domain.
The could be some elements in the co-domain that are not being used.
For a function to be one to one, then for
if and only if
For an onto function all the elements in the co-domain must be used up.
In order words, the
The condition is
Meaning each
