m∠5=22 °
Explanation:
In the diagram:
• Angles 4 and 90 degrees, are ,vertical angles,.
,
• Angles 2 and 68 degrees, are ,vertical angles,.
Since the measure of vertical angles is equal:
In the triangle:
Substitute the measures of angle 2 and 4 obtained earlier:
The measure of angle 5 is 22 degrees.
