Given:
The equation of line is
To find:
The x and y-intercept of the given line.
Solution:
We have,
Putting x=0, we get
Add 6 on both sides.
Divide both sides by 4.
So, the y-intercept is .
Putting y=0 in given equation, we get
Add 5 on both sides.
Divide both sides by 7.
So, the x-intercept is .
The red line is 180 degrees. So the arcs on top of the circle all equal up to 180 degrees. the number 72 doesn't really matter cause you're trying to find out the angle of DCE which is on the other side of the circle. So you gotta find the arc length of DE which is 68 because 180-112=68. So to find the angle, you have to divide the opposite arc length by two, which is 34.
