Answer:

x=6,\\m\angle 1=18^{\circ}

Step-by-step explanation:

Since the problem denotes the figure as a parallelogram, \overline{AB} is parallel to \overline{DC}. Therefore, angles 1 and 2 are equal (from corresponding angles and vertical angles).

Therefore, we have the following equation:

m\angle 1=m\angle 2,\\x+12=6x-18,\\30=5x,\\x=\boxed{6}

Substituting x=6:

m\angle 1=x+12=6+12=\boxed{18^{\circ}}

ASHA 777 [7]

Answer:

Step-by-step explanation:

Vertex A of the triangle ABC when rotated by 90° counterclockwise about the origin,

Rule to be followed,

A(x, y) → P(-y, x)

Therefore, A(1, 1) → P(-1, 1)

Similarly, B(3, 2) → Q(-2, 3)

C(2, 5) → R(-5, 2)

Triangle given in second quadrant will be the triangle PQR.

If the point P of triangle PQR is reflected across a line y = x,

Rule to be followed,

P(x, y) → X(y, x)

P(-1, 1) → X(1, -1)

Similarly, Q(-2, 3) → Y(3, -2)

R(-5, 2) → Z(2, -5)

Therefore, triangle given in fourth quadrant is triangle XYZ.
