First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)

The angles below form a linear pair.
What is the measure of angle ABC?

Answers

The measure of angle ABC from the given figure is 132 degree.

Given that, ∠CBD is 48°.

When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°.

Here, ∠ABC+∠CBD=180°

∠ABC+48°=180°

∠ABC=180°-48°

∠ABC=132°

Therefore, the measure of angle ABC from the given figure is 132 degree.
