Answer:

Step-by-step explanation:

The angles of a quadrilateral have to add up to equal 360.  That means that

1x + 2x + 3x + 4x = 360 and

10x = 360 so

x = 36.  Then

2x = 72 and

3x = 108 and

4x = 144

Angle A and angle D are opposite angles, as are angles B and C.  This is because opposite angles are supplementary.

Answer:

AC = 16 in.

Step-by-step explanation:

AD = CD = 10 in.

BD = 6 in.

AC = 2(AB) = ?

Apply pythagorean theorem to find AB

AB² = AD² - BD²

Substitute

AB² = 10² - 6²

AB² = 64

AB = √64

AB = 8

Therefore:

AC = 2(AB) = 2(8)

AC = 16 in.
