Answer:

The value of x is 57

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In an inscribed quadrilateral, the opposite angles are supplementary

so

m∠B+m∠D=180°

substitute the given values and solve for x

93+(x+30)=180\\x+123=180\\x=180-123\\x=57

therefore

The value of x is 57

The equation of the line in the graph is y=___ x+=_____<br> (-1,-1)
il63 [147K]

Answer:

y= 1x-1 or y= x-1

Step-by-step explanation:

Make sure we know the equation y = mx +b

Remember M= slope, B= Y-intercept

We can see that the slope (rise over run)  is 1 so we plug in the 1 for M

Y= 1x +b

Now we have to look for the Y-intercept which is -1

making our equation now: Y= 1x -1
