@mxddi3

Katrin369:

try

Katrin369:

58

Katrin369:

oops i forgot no direct answer

XioGonz:

How'd you get that answer though? like what's the equation what do I have to do

Katrin369:

Opposite angles of a quadrilateral are equal, so you would set 3x equal to 2x+20. You would find x to be 10. Because A and C are opposite each other, you can use A's equation to find the measure of C. When you substitute 10 in for x, 2x+38 equals 58.

Katrin369:

try that

Katrin369:

different things go to different people i use that method

ramen:

Also just a hint, all sides of a quadrilateral equal to what number in degrees?

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Katrin369 Opposite angles of a quadrilateral are equal \(\color{#0cbb34}{\text{End of Quote}}\) You might be thinking of a parallelogram Instead, for any inscribed quadrilateral, the opposite angles always add to 180

XioGonz:

wait I know what to do now THANK YOU

Katrin369:
