# In Exercises 19 to 26, use the drawing in which A C ↔ intersects D B ↔ at point O.If m ∠ 1 = 125 ° , find m ∠ 2 , m ∠ 3 and m ∠ 4 . To determine

To find:

The value of m2, m3 and m4.

Explanation

a. If two lines intersect, then measure of vertical angles formed is equal.

b. The sum of angles formed on a straight line is supplementary.

Given:

The given angle is m1=125°.

The given figure is,

Calculation:

From the given figure it can observed that 1 and 3 are vertical angles. The measure of vertical angles is equal.

m3=m1=125°

The angle 2 is supplementary to 3 as DB is a straight line.

m2+m3=180°

Substitute 125° for m3 in above equation.
