There are different kinds of angles. The Complete statement is that the ∠1 and ∠2 are Supplementary angles.
<h3>What are Supplementary angles?</h3>- Supplementary angles are known to be a type of angles that add up to 180 degrees.
An example, angle 120° and angle 60° are supplementary angles because sum of 120° and 60° will give you 180°. Complementary angles are angles that sum up to 90 degrees.

Depreciation involves the reduction in the value of a quantity
The rate of depreciation is about 13%
<h3>How to determine the equation</h3>From the question, we have the following ordered pairs
(x,y) = {(0,9000) and (5,4500)}
The depreciation equation is represented as:
At (0,9000), we have:
At (5,4500), we have:
This gives
Solve for b^5
Take the 5th roots
So, we have:
The rate (r) is then calculated as:
This gives
Express as percentage
Hence, the rate of depreciation is about 13%
