The sum of 1.5x and 16.5x is equal 180°.
1.5x + 16.5x = 180
18x = 180 |:18
x = 10
The angles 20y and 16.5x are the vertical angles, therefore:
20y = 16.5x
20y = 16.5(10)
20y = 165 |:20
y = 8.25
<h3>Answer: x = 10 and y = 8.25</h3>
?????????????????????????????????????
Step-by-step explanation:
y = x² - 16
x² = y + 16
x = sqrt(y + 16) because x is non-negative.
Hence the inverse function is f^(-1)(x) = sqrt(x + 16). (A)
