Question

The students in an architecture class are learning methods for measuring the widths of objects indirectly. The picture below shows that they can measure the length of AC by determining the measure of ZABC. The students have already measured ZBAC. What is the measure of ZABC? A) 90 degrees B) 45 degrees C) 180 degrees D) 135 degrees

Answer 1

The measure of angle ZABC can be found by subtracting the measure of angle ZBAC from 180 degrees.

Step-by-step explanation:

In order to find the measure of angle ZABC, we need to consider the relationship between angles in a triangle. The sum of the angles in any triangle is always 180 degrees. Since we know the measure of angle ZBAC, we can subtract it from 180 to find the measure of angle ZABC. Therefore, the measure of angle ZABC is 180 - ZBAC degrees.
