Find the measures of the remaining angles of trapezoid ABCD (not shown) if A B ¯ | | D C ¯ and m ∠ A = 58 ° and m ∠ C = 125 ° .

To determine

To Find:

The angles of a trapezoid.

Explanation

Consider the following trapezoid.

It is given that ABÂ¯||DCÂ¯ and mâˆ A=58Â° and mâˆ C=125Â°.

When ABÂ¯||DCÂ¯, the angles mâˆ Aâ€Šâ€Šâ€Šandâ€Šâ€Šâ€Šâ€Šmâˆ D are supplementary.

It means mâˆ Aâ€Šâ€Šâ€Š+â€Šâ€Šâ€Šmâˆ D=180Â°.

Substitute mâˆ A=58Â°.

Now, 58Â°â€Šâ€Šâ€Š+â€Šâ€Šâ€Šmâˆ D=180Â°
