I would really appreciate anyone who can answer this attached question, thanks.

In an inscribed quadrilateral, opposite angles add up to 180°.

So ∠A + ∠C = 180°.

(3x - 10) + 2x = 180

5x - 10 = 180

5x = 190

x = 38

The opposite angles of a cyclic quadrilateral are supplementary.

A + C = 180 degrees

3x - 10 + 2x = 180

5x = 190

x = 38

38

We know A and C add to 180 because each is half the arc subtended, A=(1/2) arc BCD and C=(1/2) arc BAD.  The two arcs together are the entire circle so,

A + C = (1/2) arc BCD + (1/2) arc BAD

        = (1/2)(arc BCD + arc BAD) = (1/2)(360) = 180 degrees

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

show us the graphs dude
