Answer:
14°
Step-by-step explanation:

We also know that ∠PQR is 76°.
So, to find ∠RQS, we can do 90°-76° = 14°
x° = 14°

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x² + 7x - 18
f(-9) is x = -9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-9) = 4(-9)² + 7(-9) - 18
- Evaluate Exponents: f(-9) = 4(81) + 7(-9) - 18
- Multiply: f(-9) = 324 - 63 - 18
- Subtract: f(-9) = 261 - 18
- Subtract: f(-9) = 243
