Answer:
<h2>m<ABD = 36°</h2><h2>m<DBC = 54°</h2>
Step-by-step explanation:
2 + 3 = 5
90° : 5 = 18
18 × 2 = 36
m<ABD = 36°
18 × 3 = 54
m<DBC = 54°

F(x) = x² - 81
Finding f⁻¹(x) the inverse function
Let y = f(x) and solve for x.
y = x² - 81
y + 81 = x²
x² = y + 81
x = √(y + 81)
Recall f(x) = y, that means x = f⁻¹(y)
x = √(y + 81)
f⁻¹(y) = √(y + 81)
Therefore f⁻¹(x) = √(x + 81)
The Answer to the question is 1.
