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.

   \frac{PN}{NL}=\frac{NQ}{NM}

   \frac{y}{3}=\frac{3.2}{4}

   y =\frac{3.2\times 3}{4}

   y = 2.4 cm

Ur missing numbers are -2, 6, and 36

Since the center point is (-2,6), the numbers are reversed in the equation to: (x+2) or(x- -2) and (y-6)

The radius is 6 units so u square it to get 36
