Need to find the values of x plss❤️

X= 30 I hope you understand the work
It can be assumed that the line is 180 degrees so you must subtract the given 90 degree angle in the middle
The equation can then be 3x=90 because if there is a x value on one you need to double it to get the other value. Then divide 90 by 3 to get 30

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
