Math Problem Statement

In the figure below, m∠ABD = 67°, and m∠1 is 5° more than m∠2. Find m∠2.

Solution

To solve for m2m \angle 2 in this problem, let's go through the information provided:

  1. We know: mABD=67m \angle ABD = 67^\circ
  2. The problem states that: m1 is 5 more than m2m \angle 1 \text{ is } 5^\circ \text{ more than } m \angle 2

Let’s set m2=xm \angle 2 = x. Then, m1m \angle 1 would be: m1=x+5m \angle 1 = x + 5

Since 1\angle 1 and 2\angle 2 together make up ABD\angle ABD, we can set up the equation: x+(x+5)=67x + (x + 5) = 67

Step 1: Solve for xx

2x+5=672x + 5 = 67 2x=6752x = 67 - 5 2x=622x = 62 x=31x = 31

Step 2: Answer

Thus, m2=31m \angle 2 = 31^\circ.
