I don't understand exactly how to solve this. Please explain if you do know how to solve this, so next time a question like this comes up I know how to solve it.

Step-by-step explanation:

116° + y° = 180°. (sum of angles on a straight line = 180°)

Therefore y° = 64°.

The angles x°, y°, 72° and 125° are interior angles of a quadrilateral. (4-sided polygon)

In a quadrilateral, sum of interior angles = 360°.

So x° = 360° - y° - 72° - 125°

= 360° - 64° - 72° - 125°

= 99°.

Hence x° = 99°.

Step-by-step explanation:

First find y as its on straight line with 116°

Now, the sum of interior angles of a quadrilateral is 360°

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
