Question

Постройте углы ADN и NDB, если ADN = 34, NDB = 120. Какой может быть градусная мера угла ADB ?

Answer 1

180-(120+34)=26° угол ADB

Answer 2

Building Angles ADN and NDB

To build angles ADN and NDB, we need to follow these steps:

1. Start with a straight line segment, which we can label as AB. 2. Place the center of a protractor at point B. 3. Measure an angle of 34 degrees counterclockwise from line AB. This will give us angle ADN. 4. Measure an angle of 120 degrees counterclockwise from line AB. This will give us angle NDB.

Please note that the angles are measured counterclockwise from the reference line AB.

Finding the Degree Measure of Angle ADB

To find the degree measure of angle ADB, we need to consider the properties of angles formed by intersecting lines.

When two lines intersect, they form pairs of vertical angles that are congruent. In this case, angle ADN and angle NDB are vertical angles, so they have the same degree measure.

Since angle ADN measures 34 degrees and angle NDB measures 120 degrees, we can conclude that angle ADN and angle NDB both measure 34 degrees.

Therefore, the degree measure of angle ADB is 34 degrees.
