Answer:

Step-by-step explanation:
Given that the angles A, B, C in a Triangle form an arithmetic sequence where A=23 degrees.
The nth term of an Arithmetic sequence is given by the formula: 
Where:
a=first term
n=number of term
d=common difference
In this case,


The sum of angles in a triangle is 180 degrees. Therefore:
∠A+∠B+∠C=180 degrees

Therefore:
Angle C,

Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = -x² + 10x - 3
g(9) is x = 9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: g(9) = -(9)² + 10(9) - 3
- Exponents: g(9) = -(81) + 10(9) - 3
- Multiply: g(9) = -81 + 90 - 3
- Add: g(9) = 9 - 3
- Subtract: g(9) = 6
