Question

6. Let the measurement of ZBAC be 86° & ZBAD be 52°. What is the measurement of ZDAC? 1380 24° 52° 340

Answer 1

To find the measurement of ZDAC in a triangle, subtract the given angles from 180 degrees.

Step-by-step explanation:

To find the measurement of ZDAC, we can use the fact that the angles in a triangle add up to 180 degrees. Since ZBAC measures 86° and ZBAD measures 52°, we can subtract those two angles from 180 to find the measurement of ZDAC.:

1. 
   
3. ZDAC = 180 - ZBAC - ZBAD
4. 
   
6. = 180 - 86 - 52
7. 
   
9. = 180 - 138
10. 
    
12. = 42°

Therefore, the measurement of ZDAC is 42°.

Answer 2

`\begin{gathered} \angle BAC=86degree \\ \angle BAD=52degree \\ \angle DAC=? \\ \angle BAC=\angle BAD+\angle DAC \\ 86=52+\angle DAC \\ \angle DAC=86-52 \\ \angle DAC=34\text{ degree} \end{gathered}`
