One of the angles, which are obtained when two straight lines intersect, are 8 times larger than the other. find these corners.

When two straight lines intersect, 4 undeveloped corners are formed. The sum of any two adjacent angles is 180 ° (since it forms a flat angle). Let us express the smaller angle in terms of x and compose the equation:

x + 8x = 180 °;

9x = 180 °;

x = 180/9;

x = 20 ° – smaller angle;

8x = 8 * 20 = 160 ° – larger angle.

Answer: 20 °, 20 °, 160 °, 160 °.
