Answer:

109

Step-by-step explanation:

line AB is 180 degrees because a circle is 360 degrees and half a circle is 180 degrees.

Add 42 degrees and 29 degrees.  42+29 = 71

Then subtract. 180 - 71 = 109

So therefore x=109

Hope this helps:)

Find the y-intercept and x-intercept of the line -x+2y=4
Alex

Answer:

The y-intercept and x-intercept of the line are 2 and -4 respectively.

Step-by-step explanation:

Given equation of line -x + 2y = 4

We have to find the y-intercept and x-intercept of the line.

Consider the given equation of line -x + 2y = 4

the y-intercept of line is the point where the line touches y axis and we know at y axis the coordinate of x is 0.

Thus, putting  x = 0 in line equation , we get,

-(0) + 2y = 4

⇒ y = \frac{4}{2}

⇒ y = 2

the x-intercept of line is the point where the line touches x axis and we know at x axis the coordinate of y is 0.

-x + 2(0) = 4

⇒ x = - 4

Thus, the y-intercept and x-intercept of the line are 2 and -4 respectively.
