Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:
![(9x+6)+(74)+(16x)=180\\](https://tex.z-dn.net/?f=%289x%2B6%29%2B%2874%29%2B%2816x%29%3D180%5C%5C)
Let’s solve for <em>x: </em>
Combine LIke Terms:
![(9x+16x)+(74+6)=180](https://tex.z-dn.net/?f=%289x%2B16x%29%2B%2874%2B6%29%3D180)
Add:
![25x+80=180](https://tex.z-dn.net/?f=25x%2B80%3D180)
Subtract 80 from both sides:
![25x=100](https://tex.z-dn.net/?f=25x%3D100)
Divide both sides by 25:
![x=4](https://tex.z-dn.net/?f=x%3D4)
Therefore, the value of <em>x </em>is 4.
Now, to find A, we can substitute it for A.
A is measured by:
![\angle A=9x+6](https://tex.z-dn.net/?f=%5Cangle%20A%3D9x%2B6)
Substitute 4 for <em>x</em> and evaluate:
![\angle A=9(4)+6=36+6=42\textdegree](https://tex.z-dn.net/?f=%5Cangle%20A%3D9%284%29%2B6%3D36%2B6%3D42%5Ctextdegree)
Hence, our answer is D.

Answer:
1 9/10
Step-by-step explanation:
3 1/10 = 3.10
1 1/5 = 1.2
3.1 - 1.2 = 1.9
1.9 = 1 9/10
Hope this helped!
