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

To find:

The value of x and m1.

Explanation

Given:

The given angle is m1=2x and m2=x.

The given figure is,

Approach:

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

Calculation:

From the given figure it can observed that 1 and 2 are supplementary angle.

m1+m2=180°

Substitute 2x for m1 and x for m2 in above equation.
