In Exercises 19 to 26, use the drawing in which A C ↔ intersects D B ↔ at point O.

If m ∠ 2 = x + 15 and m ∠ 3 = 2 x , find x and m ∠ 2 .

Chapter 1.7, Problem 24E, In Exercises 19 to 26, use the drawing in which AC intersects DBat point O. If m2=x+15 and m3=2x,

To determine

To find:

The value of x and m∠2.

Explanation

Given:

The given angles are m∠2=x+15 and m∠3=2x.

The given figure is,

Definition:

The sum of measures of angles formed on straight line is supplementary angle.

Calculation:

From the given figure it can be observed that ∠2 and ∠3 are supplementary angles.

m∠2+m∠3=180°

Substitute x+15 for m∠2 and 2x for m∠3 in above equation.
