Answer:
9 years
Step-by-step explanation:
Let's call the amount of years x. We can write
42 + x = 3(8 + x)
42 + x = 24 + 3x
2x = 18
x = 9
Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
<h3>Lines and angle</h3>
A line is the shortest distance between two points where. the points where two lines meet is an angle.
There are several types of angles including acute, obtuse, right and straight
For acute angle, the angle is less than 90 degrees
For obtuse, the angle is greater than 90 and less than 180 degrees
For right angle, the angle is 90 degrees
Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.

The seats are increasing at a rate of four per row. If you were to write this in an equation, it would be y=4X+20, with 4 as the rate of change, 20 as the original amount of seats, and Y as the total number of seats for X rows. Plug in 25 for X and you'll get an answer of 120 seats.
